Just got thre retail collector's edition. see my sig for my specs. running the latest forceware drivers. I played the demo on the previous drivers. at 1600x1200 I noticed a good improvement. also, I have 4x filtering on, yet I have chosen to leave the motion blur crap off. The environment vibrates enough on its own, the blur effect is waayyy overdone and unrealistic.
I have to think that at this point for the PC, we are looking at a minor patch to improve performance, in addition the next set of drivers (at least for nVidia owners) should get this game running smooth.
Another thing to note, I didnt find any mention of the advertising program that has been found to be in BF2142. No slip indication about the software, nor did I see anything in the EULA. I could have missed it, but I havent seen anything to indicate that BS programming is in this game.
