Uninstalled drivers. Unfortunately Guru3D's driver cleaner is no longer available. Rebooted system and search for any remnants of nvidia drivers (didn't find any). Rebooted one more time for good measure.

Install 266.58, and booted ArmAII OA. Still getting the same problems.

So....

I started from the top of the 3D properties in the Nvidia Control panel and changed one thing at a time. If changing a setting had no discernible affect I restored the settings to default.

Finally got to the Multi-GPU Rendering Mode. I assume this is SLI. I set it to Single GPU and everything worked fine. Was kinda surprised how smoothly it was running so I ran EVGA's Precision to verify only one core was being used, and it was.

So, I remember reading somewhere about a hack or trick to get SLI working. If I recall it had to do with a previous version of the game. Anyone have an idea to get both of my GPU's back in the game?

They should work automatically when you have SLI set to "nVidia Recommended". The only time you had to use a hack or trick was before the SLI profile came out in nVidia drivers. My SLI works fine, other than the driver crashes, and I'm not going to halve my performance by not using both cards. There is simply something wrong with the game or the drivers, and I'm leaning towards the game at this point, since I've never had a single driver crash with any other application, game or otherwise.

EDIT: Also, you want this if you want a driver cleaner: http://phyxion.net/Driver-Sweeper/Driver-Sweeper/

I first tried the Nvidia recommended setting with no luck. Neither do the two Alternate Rendering modes work. The problem I'm having isn't just low performance, its extreme graphical errors as soon as the main menu screen appears. Its so bad I am unable to use the main menu at all.

sadly, I've seen other examples where Arma2 does not like dual gpu cards, neither AMD or Nvidia. I mean two gpus in one card, not two cards.

what is the exe named for your Steam install?
perhaps provide some dxdiag info.

Maverick, which driver are you using?
our hardware and game settings are almost the same, except I am using ATOC=6
(i absolutely hate pixelated grass)

Currently I'm using the latest beta (280.xx), but I've had the same problem with several drivers in the past (i.e. none have really seemed better than the others)

Trying out the new drivers...

[Nikiforos]

Please give some feedback after you tested the new drivers.

Thanks

They seem about the same to me. Did get a driver crash in OA 1.59 vanilla but that's pretty common for OA in my experience.

I understand so no reason for updating the drivers I keep the old ones
