My RAID0 volume started going south on me Friday morning so I took the opportunity to wipe things clean and install Windows 7 Ultimate x64 RC (release candidate). I figured I might as well check out Windows 7 on my way towards reinstalling Vista, but I think I'm going to leave things alone for now. Note that I installed the GeForce 185.85 drivers for Windows 7. I'm a bit surpised at how much faster Crysis seems to start, exit, and play. Whereas I was playing confortably with 2x antialiasing before on Vista Ultimate x64 with SP2 beta, I am now playing at 8x just as comfortably. I can even play at 16x quite well, though the frame rate dips to what I consider sub-optimal in certain scenes. I also tried the 8xQ and 16xQ modes but Crysis locked up solid, so those two modes are out. I'm playing at 1920x1200, "Very High" settings across the board, though I am noticing that the "textures" quality always displays "Custom" after I apply the "Very High" setting. Do you think this increase performance is more attributable to the 185.85 driver set as compared to the 182.xx driver set I was using under Vista? Or do you think it is Windows 7 that attributable? The nVidia notes for 185.85 indicate that changes were made that improve permance in Crysis Warhead by up to 22%. I installed but have yet to play Crysis Warhead under this newer environment. I've seen many posts here recommending that new owners of G200-based cards use the 182.xx driver set. What are the reasons? I'd to keep an eye out for any such troubles as I move forward with the testing of additional apps. Thus far, Windows 7 has installed like a charm. No issues, no trouble installing my applications, etc. I think I'm going to leave it alone and use this release candidate for a while instead of going back to a Vista. Just realized I forgot to back up my GRID profile. Oh well... guess I'll need to redo the first 5 years of my career!
