W7 Gaming performance vs Vista

[ambam]

I heard that games actually run about 4-5 FPS faster on W7 than on Vista because W7 is far better programmed and uses less system resources. Can your OS really have any impact on gaming performance?

Yes, the OS can definitely affect game performance. That being said, I have both Win 7 Ult x64 and Vista Ult x64 (with SP2) on virtually identical machines (from a hardware perspective). Performance differences are negligible. Not surprising considering that they use the same drivers, etc.

Win 7 is indeed a better OS, overall than Vista, but it really is just the next iteration of Vista. Tweaked, more stable (at least from a clean, new install perspective), but after you install all bazillion updates and both SPs, Vista isn't as bad as the press made it out to be (and I am not a MS fanboy).

Difference, yes. A huge difference, not likely. Good luck!
