112FPS w/ SLI on 144Hz G-SYNC Monitor??

So, I just got a new monitor, the XB270HU

I've been testing my frame rates with GTX 970 SLI w/ DSR on a 1080p monitor to make sure I can handle 1440p, in games like battlefield 4, and on High settings, I was getting well over 144FPS. However, turning SLI off easily yielded over 144.

I've tried so many things, turning off Vsync/GSync completely, setting Fixed Refresh Rate in Nvidia Control Panel and Highest Available refresh rate, reinstalling drivers, I just don't get it. And it's in every game I play that uses SLI. Battlefield 4, Black Ops 3, Crysis 3, etc.

112FPS with no Vsync, and 96FPS with Vsync enabled.

HOWEVER, if I don't play at 1440p, my frame rate is just fine, utilizing both cards with no problem...So..what is it about 1440p @ 144Hz that causes my frame rate to cap itself at 96? I'm really stumped..
 
No offence but your post sounds quite confused, case in point:

So with SLI, you got "well over 144".
Without SLI you "easily yielded over 144".

BTW, with G-Sync, you shouldn't really use V-Sync.
Also don't ever use FRTC if you're on 1440p and aiming for 144 fps.

If you turn the game settings down, can you get over 96fps? If so you're running out of VRAM.

I'm nowhere near even 2GB of VRAM usage playing BF4 at lowest settings at 2560x1440, and I'm only using that as an example because my frame rate does not change whether I play on Ultra or Low, it just stays stuck at 112FPS without VSync and 96 with, and that goes for any game I try.

With SLI I got well over 144 on my old monitor that was 1080p when I DSR'd to 1440p to test my frame rates at that resolution, but when I try native 144Hz 1440p on this monitor, every game is 112FPS w/o Vsync and 96FPS w/ Vsync.

What is FRTC?

The cable could cause issues with his output to the monitor but it is not going to affect the number of frames the cards are drawing...

Maybe true, but with troubleshooting always eliminate the basics. I would also check all power cables and sli connector, make sure nothing is loose.

Monitor display properties in Windows is set to 144 Hz?

What happens when set to 120Hz?

Maybe it's the alleged gsync 144Hz bug? Or is it fixed now?

I could see the above allowing cards to hit power limits and throttle down clocks.

Another thing is the fact that this only happens at 2560x1440. If I play my game at anything below that, e.g. 1920x1080, my graphics cards do whatever they want. Change to 2560x1440, instant 112FPS cap.

Setting to 1080p 144Hz on the 1440p monitor yields higher fps?

Maybe a list of things you've tried already would help in figuring it out.

1440P at 120Hz yields what kind of fps?

I doubt it's a throttling issue if i'm understanding his issue correctly. If he's not in SLI he's able to hit the max 144fps gsync rate, with SLI enabled it drops below that to either 112 or 96 whether or not vsync is disabled or enabled.

If this is the case, enabling SLI would actually reduce the power consumption on a per card basis, with or without the issue described in that article.

120Hz, same exact issue. I really just don't understand how this is happening even with both G-SYNC and V-SYNC off.
 
Oh my god there's a new problem, I just realized that in 1080p, my FPS is capped at 170FPS with SLI. Again, without SLI, Battlfield 4 at lowest settings is easily hitting its 200FPS cap. I don't even know anymore guys. Could it really be the cable? What the hell is it about this monitor that's limiting the usage of both my GPUs? I already went ahead and ordered another cable from Amazon that won't be here Sunday but I don't have much hope.

well if you want gsync you're capped at 144fps anyway so don't kill yourself just yet

Yeah, but the problem with that is that 1920x1080 looks very blurry on this 1440p panel.

I connected my old 1920x1080 monitor back and was easily hitting the 200FPS cap in Battlefield 4 again. It is like..this monitor is somehow limiting the power of both my GPUs...
 
Contrary to what you read on the Internet Nvidia drivers aren't 100% rock solid so I'm kind of leaning that way.

What I'd do:

In Windows device manager I'd delete all monitors. You want to do the show hidden device trick option. You'll need to Google it as there ghosts depending on the OS version.

Reboot with the 1440p monitor and see if the issue is resolved. Not sure if you had to load drivers for your monitor?

Next thing I'd try is Display Driver Uninstaller and wipe and reinstall current drivers.

I don't think your last issue is an issue at all. SLI increases your total graphics power but reduces efficiency and adds CPU overhead. At 1080 with low settings one 970 is easily able to plow through the game to make your CPU the bottleneck. Enabling SLI, all you're doing is creating more driver overhead and thus reducing your efficiency and creating more work for the CPU, and since at those settings even a single 970 is enough to make the CPU the bottleneck, flipping on SLI reduced your performance because all it did was create more work for the CPU.

SLI only helps when you have a GPU bottleneck limiting your performance, it does nothing for a CPU bottleneck which is the condition you created running 1080 with low settings.

I understand what you mean but that shouldn't be a problem considering I'm running an i7-4790K @ 4.7GHz.

However, like I said, multiple tests show that on my 1080p monitor, even maxed out, it was a constant 200FPS in the firing range.

Connect the monitor, go back to firing range, 1080p on any settings is a fluctuating 150-170FPS. My GPU usage on both GPUs are in the 40s and 60s.

Tried DDU multiple times, sadly. It's a no go.

You can have a 5930k and still create a CPU bottleneck by running low settings on a powerful card. Even your GPU usage is hinting at a CPU bottleneck. I'm still not sure what the real issue is. The only way you can even go above 144fps which you seem to desperately want to do is to disable gsync, in which case you spend a lot more then you needed to on the monitor. Since it appears you don't intend on using gsync and you feel that the monitor is holding you back, why not simply return it for a different (non gsync) one?

Your complaints are also all over the place in terms of what's happening which makes it impossible to troubslehoot this for you. Mondozi gave you one example at the beginning. Another is this one right here. Earlier you said you were maxing out at 112fps now it's 150-170

EDIT: I see now you were comparing different resolutions. Never the less, all the numbers are pointing to a bottleneck, maybe it's the cable maybe it's the CPU.

FWIW, I too have a 1440p 144Hz G-Sync monitor and I just loaded up BF4

2560x1440 @ 144Hz

Low preset locks me in at 144fps. I'm using a DP cable. Specs in sig.
