Why are you trying to run G-Sync when benchmarking? All Sync options should be disabled when benching.

Gsync on vs no sync period scores are 100% negligible to non existant. If people really understood G sync they would understand it does nothing when benching. All it does it makes sure the monitors refresh is identical real time to the video cards render output.

If g-sync is enabled and you have your montior refresh rate set to 60Hz and you run 3dmark g-sync will not allow your FPS to go above 60FPS which will affect your scores big time. 

You are correct.  G-sync effectively becomes V-sync once you reach your refresh rate threshold.

Correct, if you have your monitor refresh capped OF COURSE your score goes down. But why in the world would you cap a high refresh rate Gsync monitor to begin with? You wouldn't. 

G-Sync acts just like V-Sync when it comes to refresh rate capping. You select 60Hz, it caps it at 60Hz, you select 120Hz, it caps it at 120Hz, you select 144Hz, it caps it at 144Hz. 
 
Here are my scores from running 3dmark11 with all sync options disabled inside the nvcp...
 
Graphics Test 1
166.59 fps

Graphics Test 2
226.67 fps

Graphics Test 3
280.53 fps

Graphics Test 4
128.37 fps

Physics Test
39.35 fps

Combined Test
49.76 fps

Am I going to get 166.59 fps, 226.67 fps & 280.53 fps in graphics tests 1-3 with G-Sync enabled set to 144Hz refresh rate? No, because g-sync acts like v-sync when it comes to refresh capping.

I just ran 3dmark11 with G-Sync on at 144Hz refresh rate using my PG278Q and G-Sync limited my FPS to 142 to 144FPS on graphics tests 1-3. Looks like you're wrong. Go test it for yourself. Tell me i'm right when you see it for yourself.

Exactly! But, we all just have our NVCP configured incorrectly... Yet, of course, he can't tell us how.

Funny, I get in the 200fps range. Again, something is set wrong on your end. Most likely in the NVCP too.........so common.
 
THe only other reason I can think of is the monitor being used. I use the original VG248QE 24" monitor with the DIY self install G sync kit. Unless the control module acts differently between the 2 monitors, I can go well north of 144fps recordings on benchmarks because when the framerates go north, g sync basically disengages and the program runs uncapped like V sync is disabled. Again there are about a dozen things that need to be checked off.
 
  Lastly, you do have to be in SINGLE MONITOR PERFORMANCE MODE. If your running mixed multi monitor setups toss quite a few statements I made out the window.

Sounds like your DIY G-Sync kit isn't working. Only things changed in the NVCP are... Single display performance mode is set, Prefer maximum performance is set, Preferred refresh rate is set to highest available.

I turned it off, but the performance still takes a hit.  Read my previous reply.

So you're saying you lose 1000 3dmark points just by using the PG278Q even though G-Sync is disabled when running the benchmark? This does not occur when running the PB278Q? Correct?

Yes, the performance loss is massive (IMO) in the graphics score.  With the PB278Q as the only display and PG278Q disconnected from the PC, my graphics score is around 22,500 (my max is a little more).  With the PG278Q plugged in (even if it's not even being used), the graphics score drops to roughly 20,000.  My overall score drops about 1,000 as a result.  It appears that, at least from my experiences with 2 different Operating Systems, G-sync causes a performance hit, even if it is not enabled.  It occurs when it is available as an option in NVCP, which only can be the case when a G-sync monitor is plugged into the PC.  Now, obviously this performance hit isn't the end of the world if you're already hitting 100-144FPS average in a game.  However, for games that dip down near 60, they will be dipping even lower. 
 
By the way, Battlefield 4 is now running properly for me with Rivatuner running in the background (likely due to having a clean OS or different OS).  The performance on Windows 8.1 is fabulous for Battlefield 4, as I'm hitting higher FPS on 2560x1440 than I was at 1920x1080 (I used to take a bigger hit).  G-sync will lower the FPS a little, but it is still always above 100 on most maps.  There is still slight stuttering, but this is an issue with Battlefield 4 itself.

If your using 8.1, that's an issue right there. NVCP itself does not always run properly, and a lot of the times it will hang/not respond when trying to make changes.........and many times the changes will NOT take effect properly either when you refresh. 8.1 sucks STILL IMO. Yep you gain a bit of performance in BF4(which is still negligible over Win 7 x64...........but in a lot of other games Win 8.1 actually performs no better or even worse than Win 7 x64. And if your using Nvidia's 3d vision............forget about it............

Did you not read my posts in this thread?  I tested G-sync on two different operating systems: Windows 7 and 8.1.  The issue remains the same, regardless of the OS.  You can't say that the performance gain in BF4 is negligible when going from Windows 7 to 8.1 because my experience contradicts that.  Also, please note the difference between "your" and "you're."

Well then there is user ERROR somewhere on your part then if you tested with 2 different OP systems. Fire Strike works uncapped when the NVCP is set correctly under windows 7 with Gsync? Need a video?
 
   And yes, the BF4 difference between WIndows 7 and 8 is negligible. 5% difference which is the reality on BF4 or a few FPS is negligible, the difference in reality cannot be picked up by the naked eye regardless of what the FPS counter records. If you can't physically see the difference, then its classified as negligible to me.
 
   As for grammar, relax chief, if that is something that bugs you, then its obvious you spend too much time with TPS cover sheets. 

How is there user error if I happened to upgrade my operating system around the same time I upgraded my monitor?  Upgrades often happen around the same time span.  My Fire Strike score with my PG278Q plugged in (it doesn't matter if it's even active as a primary or secondary display) can't surpass 17,000.  However, if I unplug it and have my PB278Q as the primary display, my score is around 18,000.  The main difference is the graphics score, which can be 2,000+ less with the PG278Q plugged in.  When a G-sync monitor is connected, G-sync becomes an option in the NVCP.  When this option is available, my performance decreases in all GPU-intensive applications.  You have a different monitor and completely different hardware components than I do, so it's very possible that our experiences would be different.  Hell, maybe you have the same issues as I do and you're simply not detail-oriented enough to notice or test it yourself.
 
Once again, your Battlefield 4 claim is baseless.  Battlefield 4's Windows 8.1 boost has a lot of variance, depending on hardware.  Some folks experience a smaller performance increase than others.  I just told you that I'm getting higher FPS at 2560x1440 on Windows 8.1 with the same quality settings than I did under 1920x1080 with Windows 7.  That's a VERY noticeable increase in performance.  There is also significantly-less FPS variance, which is attributed to less GPU utilization on Windows 7.  Your notion of negligible is not consistent with what most enthusiasts would agree upon.
 
Poor grammar, especially at that level, is rather pathetic and you should aim to work on that.  People are taken more seriously when they submit coherent, well-constructed, and grammatically-correct posts.
