GTX470 Performance Test Part 2: Windows 7
So the question of whether the GTX470 runs better on Windows 7 than it does on Windows XP has been answered. The answer is yes, but not by much overall. Like XP, the Win7 drivers need a lot of work. While a handful of titles like Far Cry 2, Prey and Doom 3 showed massive performance gains, other titles like UT 2004 and Pacific Assault were much slower on Win7, and offered absolutely abysmal performance. But the important fact here is that most of the other games were largely unchanged.
Since some of the scores moved around a lot by simply using a different OS, it proves the GTX470’s poor performance isn’t from architectural limitations, but rather from driver issues. On both OSes the current GTX470 drivers aren’t robust enough to handle non-standard settings in titles that are no longer “hot”, and the Win7 tests confirmed my suspicions. But the good news is that this can be fixed because I’ve seen this kind of thing many times before, including during the G80 launch days.
As of this article, all of my testing will be done on Windows 7 (64 bit). I have more articles planned for the GTX470, including an in-depth image quality analysis, a bottlenecking investigation, and some CPU scaling tests. Stay tuned.
