Yeah, basically any game that is able to play on non-standard aspect ratios (standard is 4:3 or 16:9/10 non-standard is like 36:9) can do it. Most games going to be made this year is probably going to be eyefinity capable as well games that get a patch to support non-standard aspect ratios and eyefinity.
sparkman, this would include metro 2033..it runs at my eyefinity range too..
Forget what I said earlier. Although I still don't understand what exactly you are saying, but are you saying the eyefinity isn't working on that game? I did exactly what pnico said and googled that and they (different forums) said it works on triplehead2go, which if it works there it has a pretty good chance to be compatible with eyefinity.
I just read your other thread about this topic and I see that eyefinity isn't working for you in that game. So make sure you have all the lastest drivers for your card (which is 10.3a ((which has future eyefinity features)) and regular 10.3 which is going to be released on the 24th) which will fix, as ATI claims, all eyefinity problems. After you have done that if you haven't already make sure your three monitors are made into a group (if you got the game running in eyefinity you probably have already done this) and then do the bezel correction of the monitors. After you have done all that test the game and see if it plays better.
