Aliens vs. Predator (2010)
Having the same issue. The motion blur is terrible and I don't see the MB option a lot of other posts are talking about.
The legit copy is much smoother and accually doesn't crash at all, until i used the trainer that is.
My specs are:
Intel Core i7 920
6GB DDR3 3x2GB (Triple Channel)
ATI Radeon HD 5870 1GB (9.12 Drivers)
SB X-Fi ExtremeGamer
Windows 7 64Bit
Having a Q9550, 8 Gig Ram and a GTX285 i can run it without any problem. No lags, no crashes, nothing...
Win 7 x64 too here.
Well, perhaps it was just my bad luck, all i can say is that the legit steam version works like a charm, while the Razor release missed alot of features, while they were working, you just couldn't alter them in the options.
