Hi guys,

I have recently purchased a 2nd 680 (I'm running triple screens) and have found there to be no improvement in performance in MW:O despite the card being utilized by MW as shown by MSI afterburner/HWMon/NVInspector etc..

I have tried the numerous tips on this site and others to get SLI working in this game (it works perfectly in other games) to no avail. The second card is there roasting at 65c having no effect on game performance.

So my questions, has anyone else experienced this same issue? How did you solve it? OR If there is no way to get SLI working properly with this game does anyone know how to disable SLI for just this game?

As far as I know, there is no way to get SLI working with MWO. Some people have achieved limited success trying to run crossfire with AMD cards, but I haven't read anything that I remember about people having any kind of success with SLI.

Personally, I don't know if there is a way to have your system automatically disable SLI when you boot up MWO. You will probable have to disable it manually each time you want to play MWO and enable it after your done playing MWO.

I have a GTX 295 installed and untill a few weeks ago was using it as my primary video card (I now have a EVGA 760SC as the primary and the 295 relegated to GPGPU and physX) and I can tell you MWO has no SLI support currently. I've tried creating SLI profiles, using other games' profiles and nothing has worked. Basically MWO just uses the first GPU and ignores the second so you don't need to disable SLI. Literally the second GPU on the 295 would down clock to idle speeds while the first would be running at full speed.

Support for Xfire and SLI is on the table but there is no ETA on when it will be implemented. Considering your using a triple screen setup I'd suggest if your frame rate is below tolerable levels to overclock or tweak settings. I settled on medium with a mild overclock since a single gpu on my 295 was equal to a single 275. I'm going to guess your running 3x 1080p monitors so an additional overclock if there's headroom may be worth it.

Same here. Can't get SLI to work properly on my GTX280s... I found a modified SLI profile here on the forums and while it did allow me to enable SLI, each card was only loaded %50 and the FPS was worse vs a single card.

Officially there is no support for multi-GPU rigs, yet.

People have had success getting ATi crossfire working however.

I doubt u will see proper SLI suport and scaling till DX11 is implimented.
