Hey all.
 
I'm tearing my hair out lately.  I've just built a new rig, have two EVGA GTX 770s "superclocked" ie 1110hz, and I'm looking at my FPS in Battlefield 3 and I'm getting the same FPS as a SINGLE 670/680 at 1920x1080.
 
What the hell?
 
My rig:
 
Asus Sabertooth Z77
Intel i7-3770k 3.5ghz (OC'd to 4.5ghz - confirmed using CPU-Z)
Corsair H100i Liquid Radiator for the CPU, now with stock fans instead of SP120s.
2 x EVGA GTX 770 2gb @ 1100hz "superclocked" (ie they come overclocked).
8gb Corsair Vengeance @ 1600hz (initially 1333hz but forced manually to 1600hz in the CPU OC process).
Samsung 840 Pro 256gb SSD.
Asus Xonar Phoebus Sound Car
Corsair HX850 Modular PSU (850w).
Corsair Obsidian 650d Case. Still need a 3rd party 200mm fan for the front of the case.
Windows 7 64-bit OEM.
 
In NVCP, SLI is confirmed on (tested the "Show SLI Visual Indicator" and it shows its' working in games, so SLI definitely works).
 
These are my NVCP settings:
 
Part 1 
Part 2
 
I watch videos like this for BF3:
 
Link wont work, but if you search youtube for "[2x GTX 680 SLI] Battlefield 3 B2K (Gulf of Oman)" you'll get the video I've watched.

And I freak out.   He's running 2 SLOWER cards (680s), and an i5 for god sake.  And he's getting higher min FPS figures than me.  He's seeing lows of the 80s, 70s etc.  Same map for me, I'm seeing lows of about 54 in the same areas.
 
I measure my fps using the in-game render.drawfps 1 command.  Should I use FRAPS?  Doesn't that reduce FPS?
 
I read a guy in the BF forums saying he's running max out with a single GTX 770 and on 64 man servers, he never dips below 80fps with a 3770k @4.5ghz.  How are my 2 GTX 770s running SLOWER?
 
I just don't understand what is going on.
 
I've OC'd the CPU, which makes a pretty big difference in max FPS, but I'm still getting low dips into the low 50s.
 
Here are my Heaven 4.0 results: 
 
For some reason it's saying 3.5ghz, when CPU-Z and Real Temp show 4.5ghz.  Weird.  
 
Proof from testing Borderlands 2 that it runs at 4.5ghz.  
 
Heaven 4.0 GPU Usage: 
I forgot to screenshot straight away, so it's cut off a bit.  Either way, should those spikes be happening???
 
Hyperthreading is on in the bios.  I flashed the bios the day I built the PC, so I'm running the 2003 version drivers (latest).  
 
Any ideas? 
 
[Edit] Please refer to may latter post below for a proper description of what I'm experiencing, and why I think something is just "wrong".

    Welcome to the forums 
     
    I think you meant to have several links and/or pictures in the thread, but because it's your first post that stuff isn't allowed yet (maybe have to get to 10 or 50 posts, not sure). What people often do is post the link with a space in the middle, something like:
     
    www dot evga dot com or www evga com.
     
     
    I'm sure it's just a config issue. Have you used Precision X to view your GPU usages and clock speeds as you play? How did you go about installing the driver? What does your task manager look like when you launch BF3 (i.e. number of processes)? 
     
    Edit: I see you've got pictures and stuff fixed. Now I'm going to reread it.

    First thing you should do is completely restore the defaults in the NVCP. The default settings are the recommended settings. You shouldn't even have to do the "Prefer Maximum Performance" setting like was popular during the 600 series.
     
    It also looks like you are either using the frametime or framerate meter in Afterburner. If it is like Precision X (uses the Rivatuner Statistics Server) then that is likely also causing you issues. It has been known to cause problems on the newer GPUs.

    Thanks for the fast replies guys.
     
    Sorry about the formatting.  I posted and saw it was a mess, so edited it all.
     
    To install the driver, I followed a systematic method of uninstalling individual Nvidia programs from programs in the control panel. 
     
    I had deleted the folders in the default driver location so the folder was empty.
     
    Then uninstalled the graphics driver itself, rebooted, windows installed the card (I had windows update set to let me choose so it wouldnt start installing any drivers itself).
     
    Then just installed the latest drivers (320.49) using a custom install, only installing the drivers and PhysX.
     
    I initially just installed them over the ones I got from the CD that came with the card, and since the "fresh" install of the drivers, I've seen no real performance increases.
     
    I have now defaulted the NVCP.
     
    This is EVGA Precision's GPU usage and Windows' CPU monitoring after staring at a specific spot on Tehran Highway with around 105 FPS, which is on par with a 680 SLI setup at around 1200hz and also a 3770k @4.5ghz after watching another Youtube video:
     

     
    Is this a CPU bottleneck?
     
    I had Afterburner off completely to avoid any issues there.

    dude i had the same problem but with one gtx 770 which got 5 fps on minecraft! At first, i was unable to figure out why i was getting such performance. Later i gigured out that my cpu was overheating as the cooler was goin very slow. After i went and got the cooler master hyper eve, i got 900-1000 fps on minecraft and 120-130 fps on bf3! Check your cpu and make sure both gpus have power and are correctly in sli. If not maybe you got a bad card or maybe your gpu is overheating.
     
    Good Luck!

    Your heaven bench is normal for 770 SLI, I'm just on a single 770 with a score of 987 which is half what you have.

    Welcome to the EVGA forums
     
    First off, pay no attention to you tube vids and peoples settings and framerate claims...
     
    Do--> pay attention to your system launch configuration (background overhead) and your browser launch condition.
     
    Keep your NVCP at defaults and -always- run BF3 testing full screen at native res 
     
    BF3 suffers from framedrops -period- 
    The way to increase minimums is careful attention to your config details, launch condition and in-game settings
     
    Please post a full screenshot of your BF3 in-game video options panel for review

    Thanks for everyone's input so far.
     
    My BF3 settings with GPU and CPU usage: 
     
    My CPU temps after an hour of play on a mixture of games, were 67c on 1 core and 58c on the coolest.
     
    My GPUs never go above about 64-67c.  
     
    Ambient room temp is maybe 20-23c.

    Reading of the thread and looking at your screenshots and actions taken so far...
     
    NVCP at defaults is good
    Temps look ok (cpu/gpu)
     
    All BF3 in game settings look ok except for the colorblind
    -->Colorblind support... turn it off
     
    I also suggest uninstalling Precision
    *answer NO when asked to save profiles and data
    reboot once after its uninstalled
     
    Do the --EXACT-- same posted above with your Afterburner as well
     
    Then (after rebooting) reinstall either one or the other (Precision or Afterburner) and do not put the other in without uninstalling the other. 
    Skip the RTSS add-on install and leave the program at -defaults- except to start with windows and user fan profile.
    *the clocking is fine, I am taking about changing the internal program settings and graph display additions...
    -------------------------------------------------------
     
    BF3 performance is effected by your systems launch condition and "other" factors (a few are listed below)
     
    First: is the number of background programs and Processes that are running. The cleaner your system boots, the better the game will run.
     
    Second: Your browser version and loading can have a strong effect on BF3.
    I suggest Chrome set to launch -untabbed-, Flash and browser cache entries cleaned for best Battlelog launching condition. 
     
    Third: USB devices can have a effect on FPS in BF3
    I suggest testing USB polling, by opening TaskManager/Processes tab on the -desktop- and then watching your CPU use percentage as you move the mouse in 5in circles around the screen....
     
    NOTE--> do NOT run more than one instance of GPUz at a time (as possibly serious issues could occur)

    Re:GTX 770 SLI Seemingly Under-performing. 2013/07/30 04:45:12 (permalink)
    Thanks for the support Maniaac.  Really appreciate it.
     
    I'm at work at the moment, so I won't be able to run anything for the next 4 or 5 hours.  
     
    But when I get home I'll uninstall Afterburner and say no to profiles, reboot, uninstall Precision, no to profiles, reboot.
     
    Then re-install Precision after downloading the latest version, make sure it's default, set the same OC.
     
    Then do you want me to run BF3 again posting the same image as above after turning off colourblind? (What does colourblind change processing-wise?) 
     
    Any additional programs you want me to run?
     
    I'll go on the same map (Wake Island) as well to make it fairer.  
     
    I know that BF3 is CPU intensive, so having an empty map is quite biased I guess.
     
    [Edit] I feel I should point out, that these low FPS moments are not drops.  They're not "spikes".  I have about 4 or 5 other threads going on various forums from official Nvidia to Overclockers UK to Reddit posting my problem, and it seems a lot of people are assuming these are in fact moments of low FPS followed by high.  A quick drop followed by normal levels again.  This is NOT what is happening.
     
    The problem I am facing is having a consistent "low" FPS of, say, 55, looking at whatever scene, when a similar setup to mine, in the same scene, is getting 100+.  I don't "constantly" get 50-60 FPS, it just stays hovering around those figures, then I turn and it jumps to, say 140, turn somewhere else, 90, somewhere else, 160 etc.  Looking at an Afterburner Framerate graph is like looking at a mountain range, which is expected as of course FPS figures fluctuate depending on what is going on, where you are looking etc.  I just find it hard to believe my "lows" are in the 50s, when less powerful cards, EVEN SINGLE 770s, never go that low.
     
    So for example, say I spawn at flag B by the ocean in Gulf of Oman and look toward the skyscrapers in the middle.  I test on Gulf of Oman because those skyscrapers are widely accepted as being the single, toughest-on-hardware area of any map in Battlefield 3. 
     
    I get about 56-60 FPS standing still on a 64-man server looking at those skyscrapers.
     
    I know it should be ignored, but I look at a Youtube video of someone with an i5 and SLI 680s, same map, 64-man, at B flag, and when he turns and sees the skyscrapers, same spot, he's getting 100+ FPS.
     
    For me to have more powerful cards (I know the 770s are basically 680s, but with GDDR5 and a higher core clock), AND an i7, getting less FPS or not being as constistently over that magical 120 FPS mark that even slower cards than the 770s in SLI can achieve with the same CPU as me, I can't help but think something is wrong.

    The 680s have GDDR5 as well. You're looking at maybe a 10% increase from 680 to 770 at stock. And the i5 is not a bad processor.... The only difference between it and the i7 is the hyperthreading, which most games don't support, yet... There are even some games where hyperhreading actually hinders performance. Clock for clock with hyperthreading disabled, the two run similar... His cpu is even OC higher than yours in a game which more cpu dependant than others.

    Your mins are dipping lower than his, but many factors come in to play. Looking past the cpu and gpu (as you should in this case...), you have to look at drivers, hardware specs, background programs, and browser settings which are most likely whats at fault here. Besides, your magic number should be 60 and not 120 since you are running on 60Hz.

    EDIT: the only thing I would more closely rely on when comparing different systems are standard benchmarks (unigine, 3d mark.....) which would test all systems much more equally than playing the same game with same settings as someone else...

    Hey maniacvvv, I have a question related to this(don't mean to hijack this topic so if you would rather respond in a PM, just pm me). Why do these seemingly unrelated settings affect Battlefield's FPS? Do you have any idea, for example, why having a USB drive plugged in could have a negative impact on the way a game runs on your system? It is just an issue of system resource allocation, or is this particular game running scans on the system perhaps that can cause processing latency? I totally buy that many minute settings have an effect here, as they are testable and provable, but do you have any theories as to why these things affect this game?
     
    @OP - You're in great hands, listen to maniac, I've seen him help others aplenty.

    Irony being I'm about to start unpacking a BenQ 120hz monitor.
     
    I agree there are many factors, and I didn't realize (clearly) that an i5 was extremely similar to an i7 bar the hyperthreading.  I'd imagine Battlefield 4 will utilize it, if only a few games are doing it at the moment.
     
    He's running a higher ghz than me, sure.  Is .2 ghz REALLY going to see a 20+ fps increase in a cpu-intensive game like BF3?  Ignorance, naivety kicking in I'm afraid on my behalf.
     
    Browser settings?  Really?
     
    I'm running 8gb at 1600hz, single stick.  Loads of people go with 16gb but these days that's apparently overkill.  I doubt it would have much affect?
     
    I've certainly installed the Nvidia drivers as cleanly as possible, as recommended by the official Nvidia forums, following it step by step.  Making sure Precision was off completely and not starting up with windows etc.  
     
    HD audio is off in the bios.
     
    I know Intel have their own graphics on their chips.  Not sure where in my bios the option would be to make sure the onboard graphics is disabled.
     
    Going to setup this new monitor, then uninstall Afterburner and Precision as recommended above.
     
    Loads of things are going through my mind.  Is the CPU bottlenecking.  Nobody has confirmed that yet.  Is one of the GPUs defunct in some way.  Is my RAM enough.  Is everything seated properly.  
     
    I'm seeing those spikes in the Heaven benchmark results above where I show the GPU usage, and I see those spikes in the GPU Usage AND power supply, which makes me think something is wrong.  I'm non-the-wiser these days, it's been the best part of half a decade since I had a dedicated gaming PC.
     
    Oh, forgot to mention I've tried both cards individually a few days ago.
     
    I did some testing on Borderlands 2 as I was worried about low FPS in that game too.  I ran a thread that has yet to conclude what the "problem" is, but I was advised to try each card individually installed to see if one was acting up.
     
    Here are the results of each card's GPU usage etc.  I did the same as I did above for BF3 - look at a low FPS area for a few minutes, then a high and screenshot the graphs.
     
    Can anyone confirm that a GPU should be behaving like this?:
     
    Card 1:
     

     
    Card 2:

    Reading of the thread and looking at your screenshots and actions taken so far...

    NVCP at defaults is good
    Temps look ok (cpu/gpu)

    All BF3 in game settings look ok except for the colorblind
    -->Colorblind support... turn it off

    I also suggest uninstalling Precision
    *answer NO when asked to save profiles and data
    reboot once after its uninstalled

    Do the --EXACT-- same posted above with your Afterburner as well

    Then (after rebooting) reinstall either one or the other (Precision or Afterburner) and do not put the other in without uninstalling the other. 
    Skip the RTSS add-on install and leave the program at -defaults- except to start with windows and user fan profile.
    *the clocking is fine, I am taking about changing the internal program settings and graph display additions...
    -------------------------------------------------------

    BF3 performance is effected by your systems launch condition and "other" factors (a few are listed below)

    First: is the number of background programs and Processes that are running. The cleaner your system boots, the better the game will run.

    Second: Your browser version and loading can have a strong effect on BF3.
    I suggest Chrome set to launch -untabbed-, Flash and browser cache entries cleaned for best Battlelog launching condition. 

    Third: USB devices can have a effect on FPS in BF3
    I suggest testing USB polling, by opening TaskManager/Processes tab on the -desktop- and then watching your CPU use percentage as you move the mouse in 5in circles around the screen....

    NOTE--> do NOT run more than one instance of GPUz at a time (as possibly serious issues could occur)



    Hey maniacvvv, I have a question related to this(don't mean to hijack this topic so if you would rather respond in a PM, just pm me). Why do these seemingly unrelated settings affect Battlefield's FPS? Do you have any idea, for example, why having a USB drive plugged in could have a negative impact on the way a game runs on your system? It is just an issue of system resource allocation, or is this particular game running scans on the system perhaps that can cause processing latency? I totally buy that many minute settings have an effect here, as they are testable and provable, but do you have any theories as to why these things affect this game?

    @OP - You're in great hands, listen to maniac, I've seen him help others aplenty.

     
    I will send you a PM

    Irony being I'm about to start unpacking a BenQ 120hz monitor.

    I agree there are many factors, and I didn't realize (clearly) that an i5 was extremely similar to an i7 bar the hyperthreading.  I'd imagine Battlefield 4 will utilize it, if only a few games are doing it at the moment.

    He's running a higher ghz than me, sure.  Is .2 ghz REALLY going to see a 20+ fps increase in a cpu-intensive game like BF3?  Ignorance, naivety kicking in I'm afraid on my behalf.

    Browser settings?  Really?

    I'm running 8gb at 1600hz, single stick.  Loads of people go with 16gb but these days that's apparently overkill.  I doubt it would have much affect?

    I've certainly installed the Nvidia drivers as cleanly as possible, as recommended by the official Nvidia forums, following it step by step.  Making sure Precision was off completely and not starting up with windows etc.  

    HD audio is off in the bios.

    I know Intel have their own graphics on their chips.  Not sure where in my bios the option would be to make sure the onboard graphics is disabled.

    Going to setup this new monitor, then uninstall Afterburner and Precision as recommended above.
     
    Loads of things are going through my mind.  Is the CPU bottlenecking.  Nobody has confirmed that yet.  Is one of the GPUs defunct in some way.  Is my RAM enough.  Is everything seated properly.  

    I'm seeing those spikes in the Heaven benchmark results above where I show the GPU usage, and I see those spikes in the GPU Usage AND power supply, which makes me think something is wrong.  I'm non-the-wiser these days, it's been the best part of half a decade since I had a dedicated gaming PC.

    Oh, forgot to mention I've tried both cards individually a few days ago.

    I did some testing on Borderlands 2 as I was worried about low FPS in that game too.  I ran a thread that has yet to conclude what the "problem" is, but I was advised to try each card individually installed to see if one was acting up.

    Here are the results of each card's GPU usage etc.  I did the same as I did above for BF3 - look at a low FPS area for a few minutes, then a high and screenshot the graphs.

    Can anyone confirm that a GPU should be behaving like this?:

    Card 1:



    Card 2:



     
    Running a non-HT CPU will crimp performance a bit... as you have only half the threads.
    Running a single stick, will default the RAM to single channel.... this will cut ram bandwidth in half
     
    As far as the cards go, everything in the screenshots appears just fine.
     
    I am extremely busy today with doing some builds and testing the new BETA driver....
    Get your new monitor hooked up and then PM me tomorrow night.
    I will PM you my phone number and we can get you setup perfect for a 120hz and BF3
    I should have some time wednesday night or thursday

    Appreciate the offer my friend, I'll take you up on that if I remember.
     
    Well, I set up the new monitor.
     
    And just...wow.  Wow.  120Hz is the future.  Ridiculous fluidity, I've been seriously missing out.
     
    Anyway, back on track.  I uninstalled Precision and Afterburner one after the other with answering no to the settings as well as restarting between uninstalls.
     
    I downloaded the latest Precision version after installing the new monitor, fired that up, set it to start in Windows, unlinked the power and temp target, set the power to 106%, temp to 85, and put +90hz to the GPU.  Apply, then minimized.
     
    Logged in to a 64-man version of Gulf of Oman.  
     
    Went to flag B, looked at the skyscraper area and...
     
    65-70FPS, holding.
     
    An increase then.  
     
    Some running around for 10-15 minutes and I've noticed LESS dips into the 50s, but they're still there.
     
    I think my mind may be tricking me though, as this is the first time I've ever sat infront of a 120hz monitor, so even at 70 FPS, it feels FAR, FAR, FAR faster than 60hz.
     
    Instantly noticed the difference.  I was therefore looking less at the FPS figure as I was playing.
     
    Making progress it seems.

    I don't think there is anything wrong here to be frank. I run SLI 770's SC as well.
     
    Your cards are performing as expected, also don't be surprised if an OC'd i5 could outperform your CPU. I run an i5 clocked at 4.8, that along with +100 on the GPU's and +400 on the memory just that in itself might be enough for me to look at the skyscrapers and have a few more frames.
     
    Quit fretting, enjoy your game.

    I've followed Dynasty over here from the nVidia forums, I'm having the exact same problems with a single gtx770. I'm aiming for 120fps but sometimes the card will sit at 60fps and 65% GPU usage. Exact same problem on Noshar canals with prolonged frame dips to ~60fps while the GPU derps around at 65% usage.
     
    It's NOT a CPU bottleneck, I can say that for sure. I'm running an i7 3770k @ 3.64ghz and only Farcry managed to max out one thread.
     
    GPU load appears to be settings and game dependent. Examples:
     
    BF3, Farcry 3, and Grid 2 will run at 100% GPU usage with AA/postFX ON, but at ~80% with it OFF. In the case of BF3, this is specifically centered around AA deferred.
     
    SW:TOR wouldn't go above 65% usage no matter the settings.
     
    Other stuff like War Thunder, the Heaven benchmark, Bioshock:Infinite, and Skyrim will happily bop to 100% GPU usage no matter the settings.  Skyrim was a little funky but it was never designed to go above 60fps, so meh.
     
    My card (Gigabyte GTX770 windfore 3x OC) comes overclocked out the box, but I did try a little overclocking to see if it would make a difference, and it was very minimal (~5% fps gain for a 10% OC on an already 10%+ OC'd card). Not worth the risk for me.
     
    So, I'm not sure at this point... driver issue? Coding issue with the games? Legacy issue with how games allocate resources on the card?
     
    One thing I've noticed is I never seem to drop below 60fps. The card doesn't seem to give a hoot about GPU usage above 60fps, but as soon as it starts to approach that it jacks up the usage. I wonder if the cards are optimised for pulling 60fps and they forgot about us 120hz+ people?
     
    I've posted a set of screenshots for the above here:

    A single 570 is not dual 680's in SLI in terms of CPU overhead...
     
    While many games and apps do not take advantage of HT or use it poorly...  
    The OS and Nvidia drivers are highly thread independent, and many of the patch performance improvements in BF3 from DICE and Nvidia drivers use thread distribution to do so.
    *this was not as important over a year ago at BF3 launch, but it has become more so over time

    You "competitive" guys are listening to the most uninformed sources for information...
    Your information is out of date for modern gaming engines and hardware
     
     
    -->The AF setting has -zero- performance cost and is the -primary- way of making targets/textured objects edges more defined.
    Anyone playing BF3 without this setting at x16--> is at a serious disadvantage against others
     
    Use of a secondary display for BF3? well that speaks for itself

    Actually, 16x saw a small drop on my 560's, hence the 8x. Probably won't make a difference on the 770, I've just had bigger concerns.
     
    Second monitor is used for maps, mumble, scoreboard, etc. It might have a bit of a performance impact, but it's utility more than makes up for it. I know very few comp players who don't use a second monitor.
     
    But, you clearly know everything and I'm ridiculously ignorant, outdated and uninformed.
