name demanding game not crysis bioshokc UT3

what are some pretty demanding games that dont include crysis bioshock, and UT3 (just got an x1950pro so i want to play a demanding games for testing)sabbath2gamer

World in Conflict

Rainbow 6 Vegasacsguitar

It is quite demanding on hardware actually. It uses the same engine (Unreal) as BioShock, but BioShock is better optimized and will run more easily than Vegas on low end hardware.

Company of Heroes kinda

World in Conflict definitely

That's all off the top of my head
