We encountered an annoying bug with NVIDIA's Forceware 162.22 for Vista. You'll get slowdowns whenever you apply system changes in Quake 4. To workaround this, we had to restart the application after changing resolutions and / or applying AA and AF. A quick glance of the graph shows that performance differences between Vista and XP are negligible, though they are present. Funny, the Radeon X1950 Pro seem to get slightly faster with Vista as we use higher resolutions, probably due in part to AMD's new OpenGL drivers. The GeForce 8600GTS is slightly slower with Vista by about 7 to 10 percent, though you'll likely won't notice the difference ingame.
