Thumbs up Re: Enabling SLI causes slow 2D and high CPU load

I just wanted to give you a little update. I just installed the 285.05.09 drivers (latest 3.0 kernel, xorg 1.11.1). I don't know what they did, but SLI+BaseMosaic now seems to work perfectly for me.

Performance is great, just as good as with a single card and screen (compared with the Heaven benchmark). Now I see how bad the performance was when I was using Xinerama to drive my three-screen setup (less than half the FPS).

I hope there won't be any surprises still, but as of now, it works great. I recommend everyone with similar issues to try the latest drivers. Now I'm looking forward to try compiz on all monitors. ^^
