XP SP2 vs. Vista RTM vs. Vista SP1: Gaming benchmark

Adrian Kingsley-Hughes from ZDNet.com executed the tests using the AMD Phenom 9700, Radeon 3850 graphics card, 2GB of RAM and ATi Catalyst drivers 8.2.

The three games which performed better on Vista than on XP SP2 were Call of Duty 4, F.E.A.R. and The Elder Scrolls IV: Oblivion.
Vista gave The Elder Scrolls IV: Oblivion the best performance boost compared to XP SP2, working out at an average of 9 frames per second faster on Vista RTM and 13 frames per second faster on Vista SP1.

Seven out of ten of the games tested produced frame rate averages which were lower under Vista than XP SP2, however, a closer look at the numbers shows that when Vista is slower than XP SP2, the actual frame rate differences are only in the single digits.
