[quote]Yes, window mode works. BUT, you will lose nearly 50% performance. I dropped from 60 to 30 FPS while in window mode and you have to drastically decrease graphics settings to make it not stutter all the time. AND, it doesnt change the stretched light effects. So for me its complete unplayable in that state and went back to single monitor.
I would think over the Grade "A" as well. The Beta was, the release not anymore.
According to my knowledge the windowed mode disables support for crossfire (100%) and most likely for SLI as well. This explains why your FPS halved.
Btw I tried to run BF3 on my crossfire AMD 6850 1GB and in 5760x1080 with lowest details I had like 15FPS.
This game is poorly optimized considering that I don't see any graphics orgy...
You're just running yourself out of VRAM. Why would you try to 5760x1080 this game with a 1Gb card and call it "unoptimized" Rofl.
