Hi all,
 
 I'm looking to add a 2nd Titan X to my pc , so i can run most games(i hope) in 4K/60fps,
maxed out(without AA).
 
 But i'm not sure how nvidia has improved micro-stuttering since i last SLI'ed
a couple of (i believe?) 570's.
 
 I'm picky with a smooth image as i'm looking to be picking up a g-sync monitor(4k)
once these are out in IPS panels(ie..Asus's new 4K this fall).
 
 But if i'd be getting bad micro-stuttering i'm concerned it may defeat the purpose of
g-sync?
 
 So for those whom SLI(2 way), do you notice micro-stuttering?
 
 And do most games work well with SLI?
 
 TIA 
 
 
 
 
 

I am currently using sli TX and I had terrible stuttering.  I could watch the gpu usage going up and down (using open hardware monitor) , as if some one was mashing the throttle and lifting back off, constantly.  This occurred equally with 3-way sli, 2-way sli, but was not a problem when disabling sli (single gpu).
 
  Enabling global triple buffering (nvidia control panel) and leaving any graphical setting with a multiplier (x4,x8) off has been my cure for it.   I guess the triple buffering keeps a load on the cards as evidenced by smoother gpu load trending.  This is running 4k (2160p) on the display port.  
 
I could easily test the stuttering using gta in game map.   All I had to do was scroll around the map and it would start stuttering and wouldn't stop.  Driving vehicles was very difficult while it was stuttering and forget about trying to aim and shoot, impossible.
 
Edit: Windows 7 ult 64bit

No one makes a 40 inch 4k G-sync monitor ..... yet.   If they could just keep the cards loaded in sli instead of cycling the load on/off the stuttering would go away.

There is soo nooby, When i hear people say Microstuttering,    Now that i have G-sync Enable all the time, With Vertical Sync OFF,  There is non Microstuttering or stuttering,, Dosent matter how many cards there is!   I had 4x Way sli Titans,  and 4 way sli 780TI classifieds, and now 2x Titan X Oc to about 1.470ghz+ memory 300+, With G sync

There is no microstuttering to see,    Playing games today whiout G sync its just a bloddy mess, Then i agree about stuttering and tearing,  But With G-sync there is none,  Start buying a G-sync monitor with sli or just 1 card with Rog swift or others with it, Rog swift IPS 144Hz G-sync from asus will be in this year to :) I think soon,  Gonna sell my TN rog and uppgrade to ips,  Gaming at 4K today at 60hz Is no need actually, Pick upp rog or the new one at 1440P  You dont see that much of a diffrence from 1440p to 4K,  Now that i have played on 5K, The quality getts better of course, But no need 

Nice rig would love to see more pictures of that thing!

Thanks! :)  here is a link for the lastest builds  http://startiger.imgur.com/all/#1

Nice, but am I right in saying that there is only one 360 Rad cooling all those components? Nice looking build for sure, but can't be very cool?

1 single 360rad does the jobb , it is push and pull and thick to,  will be lower temps with more rads, But still doing it nice,

I've heard some people have issues with micro-stuttering but I've not seen the issue in my scenario.  Granted I'm only driving a 2560x1080 @60Hz so it's not difficult for my GPU's to push.  I do have to run Vsync to avoid screen tearing, though.
 
In one case, a user mentioned migrating to Win8/8.1 resolved his issue with stuttering but I can't recall what his display set up was.
 

 
Micro stuttering... ??? NVIDIA is still better on that field than red crew.
Look on screen of Unigine Heaven 4.0 behind card...Many people notice that and ask why that happen...
Many AMD graphics start to behave similar in games with PhysX but people with GeForce still not complain on that...
That's driver, nothing else...
 

 
 
 

Nvidia drivers is better than amd for sure,  But Buy a G-sync monitor all the stuttering and tearing will be gone  Problem solved :)   that on the monitor right there, That was big time stuttering,

Gsync is a god send. I never even noticed what micro stuttering was, til i got a g sync LCD ( the swift ) and tried turning it off after using g sync. Now i know exactly what it is, and its annoying. G sync is awesome.

So with SLI and Gsync micro stutter isn't noticeable? ????
 
can someone give a confirmation on that? Thanks!

Thanks, i was hoping Gsync reduced stuttering, and glad you confirmed it.
 
In your opinion, with 2 Titan X's, should i go with a 144hz 1440p IPS, or 4K/60hz?
 
I'm leaning towards the Acer 1440p panel, but in seeing just from using DSR at 4K, how crisper
the entire IQ is, i'm not sure which way to go here.
 
[Ideally a 4K/60 IPS with an option for 1440p/144hz would be a dream, but i'm sure that won't be a reality in the near future]
 
 Thanks again.

i went with 1440 cause i want to keep the fps at 144 fps or as close as possible at all times. 4k limits you to 60 fps, and ill never go back to 60 fps again, after seeing 120/144 hz/fps.

Funny if you saw 4k you'd definitely not go back to 1440p!

ARMYguy
I am not so sure about that. I have ran at 4k using DSR and while it looks better ( how could it not ), the idea of being stuck at 60 fps is an automatic no go. Did you know a CRT from the 90s could show more than 60 fps? Enjoy your 1995 tech, ill enjoy the response and fluidity of 144 fps !

Considering CRT TV's were standard def I would l love to know what you were smoking to see 4k in 1995?

I think what he means is that 60hz refresh was surpassed in the 90's with CRTs of the time.  Now with new 4k monitors we are "back" with outdated refresh rates.  I have to agree with him.  A major reason I have not gone 4K full time yet is that I hate 60hz refresh.  Although the resolution is obviously better the smoothness of 120 or 144hz is noticeable.   G sync helps, but 60hz is still 60hz. 

Response time is much more important for twitch gaming. Anyone who thinks they can tell the difference between 60 - 144fps is fooling themselves. The human eye cannot tell the difference at anything over that, whereas the human eye has no perceived limits to resolution... 4k is nothing to what the human eye can actually see.

some might say they cannot tell the difference, but I can assure you it does decrease the response time giving you extra speed by a little (The time it takes for an action to happen on a screen)
 
Those high refresh rate monitors are good for people want that edge response time against their enemy in any game. So 144hz makes the difference, if it did not make the difference then there would be no market for those refresh rates....

I think someone is getting confused between response time and refresh rate...

I had that Acer monitor at release.  Mine, unfortunately, had some QC issues and I returned it.  Having said that, I personally wasn't overly impressed with the high refresh.  It did have a nice image aside from the QC issues.  I don't play a lot of twitch shooters, so that may be a big part of it.  Had the refresh rate impressed me, I probably would have done an exchange until I got a good one.
 
Using DSR is nothing like using a 4K panel.  It makes the image better on the lower res, sure, but it can't display more pixels than it has.  It can simply clean up the image.  Period.  I am still debating on a 4K monitor myself, but I am currently most interested in the new 21:9 3440X1440 IPS GSYNC panels coming out from Acer and ASUS.  I love that format on my current monitor.
 
People can offer you their 'opinion' all day long.  Some will swear TN isn't important over IPS (I disagree).  Others will tell you they can never live without 144Hz again (I disagree).  I would personally recommend finding a way to physically see both.  Local store?  Friends?  Purchase both from a location where you can return the one you don't like as much?  Having seen the 144Hz made me less concerned over it.  Having seen a 4K monitor I was impressed.  Having tried GSYNC... now that is definitely worth having in my next monitor.

Actually, humans can perceive and identify images with a persistence time of less than 1/1000th of a second. Humans do not actually see the world around them in FPS.  Input lag, refresh time are important. Your response time is irrelevant if your display updates slower than your ability to process the information and react.

I like 4k 60hz over 144hz 1440p monitor.
 
- I can really agree with that, but I did a blind test with a friend of mine, one monitor was 144hz  and the other was 60 hz
- Both of them were at 1440p
- same monitors
- no fps overlay
-Test range in bf4, I was always able to tell the difference even when they switched it around or even faked switched it around
 
Conclusion: Everyone is different I guess?
