Sorry to say, you are slightly wrong. I tried Quake 4 on Vista 64, and
the game wouldn't run at all. I got so disgusted with a pretty good
portion of my games not working on Vista 64, I removed it from my
system, and went back to WindowsXP for the time being.
Works fine for me. I'm also running Vista64. When did you last try, eight
years ago?
Early on, Vista video drivers weren't handling OpenGL very
well, if at all. Most recent drivers are a lot better.
The *only* problem I have with Games and Vista64 is BF2... Vista tends to
bluescreen on my while while loading the next map. I seem to be in the
minority there, too, as most people claim it works fine for them with
Vista.
