SLI and ARMA3
Have x2 980ti's and wondering
1)Does ARMA3 support SLI?
2)How do I enable SLI ingame? - note I can see in the nvidia control panel I can activate SLI - but do I then need to select a profile from somewhere?or is enabling it in the control panel enough to get the benefit?
Any help appreciated........

dont bother as this game doesnt scale really at all with sli/crossfire setups, run a single card. also you wont get a performance increase anyhow in most cases here

tk thanks for the reply.....
interesting because when i enable the sli (from control panel)my fps (4k monitor) seems to have improved up to around 50 fps from around 35-40....but not sure if this is because of the new apex engine or the sli (note I am running the same SP mission each time)

also more general question - how do you actually enable sli in a game that supports it (for example bf4)...?

oh your running 2160p, i figured it would have been 1080/1440 like most folks here. the higher the res the more gpu usage arma takes up while performance still stays about the same so some extent. it would be due to sli, theres no new engine for apex.

YES 4K monitor with g sync 3840X 2160........................................................but by just enabling sli in the nvidia control should it work? no need to select a profile from software like nvisia inspector?

im jelous lol. and forcing it in the control panel should work without issue, run a overlay and see if both gpu's are going under load and that will tell you.

1) Yes. Arma 3 works with SLI - BUT, be warned about the PIP ((Picture-in-Picture(mirrors-screens in vehicles etc)) function will cause very bad flickering in them due to SLI for some odd reason. I've just grown used to it, unfortunately.

2) SLI in Arma 3 is all based on just having it enabled through the NVIDIA control panel. That is all you need to change. No profile needed to select. It works by default.

IMO, SLI doesn't seem to do MUCH for me since I only play at 1920x1080 - 100% sampling. But in your case, @4k resolution, I think it would very much do you some good.

TK thanks - i get the feeling it is having a good effect as on as single card was not getting 50-60fps....
How do you bring up the overlay to check if its working? and for other games (BF4 for example) how are you ment to run the SLI?(or is switching it on the control panel enough?)

use something such as msi afterburner(my preference), go to settings and then the monitoring tab and enable your gpu usage and show in on screen display.

I personally use MSI Afterburner with RivaTuner that comes with it, to monitor/customize what you want to be shown on the overlay.

Most games that support SLI by default, will automatically support it as long as you have SLI enabled through the NVIDIA control panel.

5930k @4.5Ghz, 980TI SLI here: running YAAB @7680x1440p I only get about 32FPS average on ultra settings; same @2560x1440p.

On my 4770K @.4.3Ghz with 780Ti SLI I get about 34 FPS @2560x1440p and about the same @1920x1080p on ultra settings.

Seems to not do much.

Just to update this since I don't see a ton of info on this lately, but I just ran the YAAB on a few systems @1080p ultra (vsync off obviously).

i7 6700@4.0Ghz/SSD/16GB DDR4 2133Mhz/GTX 1070FE 8GB = 35.5 FPS

i7 4770K@4.3Ghz/SSD/16GB 1600Mhz DDR3/MATRIX GTX 780Ti 3GB = 38.7 FPS

i7 4770K@4.3Ghz/SSD/16GB 1600Mhz DDR3/MATRIX GTX 780Ti SLI 3GB = 36.6 FPS / 39.3 FPS (two runs ~37.95 FPS average)

i7 3930K@4.2Ghz/HDD/16GB DDR3 1600Mhz/STRIX GTX 1060 6GB = 36.7 FPS

i5 6600K@3.9Ghz/SSD/16GB DDR4 2400Mhz/STRIX 390X 8GB = 32.0 FPS

i7 6820HK@3.8Ghz/HDD/16GB DDR4 2133Mhz/Laptop GTX 1070 8GB = 31.8 FPS

i3 6100@3.7Ghz/HDD/16GB DDR4 2133Mhz/EVGA GTX 1060 3GB = 28.95 FPS

So it would appear to me that ArmA 3 a.) doesn't care too much about the GPU b.) Definitely doesn't care about SLI
