Yesterday I started playing ArmA again and it was running fine on normal/high settings. I googled how to increase performance and found out turning off SLI gives you an FPS boost, I turned it off ran the 1 card at 99% and i was running ArmA II on max settings at 1920x1080 res, was great.
An hour or so later I started another campaign mission and my fps went from a solid 55-60 to no more than 10, and now even if i tweak my video settings i cant go above 20....What the hell have i done?
Specs:
Asus Extreme4 Gen3 Motherboard
i5-2500k @ 4.5GhZ
2x GTX 560Ti (SLI)
8GB G-Skill Ripjaw (1600mhz)
60GB Patriot PYRO SSD
500GB Samsung T1 HDD

I am not sure if this is relevant, but to use 2 GPUs with ArmA II you must have "-winxp" as a startup command. This may give you an FPS boost and allow you to use SLI.
