Which OS do you prefer to play games on?

Vista has been out a while now and initially there were a lot of complaints about numerous games not running on it due to various incompatibilities.

Which Operating System (OS) do you prefer to play games on and why?

For me it would have to be XP because my computer isn't powerful enough to play games with Vista on at the same time.

I've heard of many reports that the Oblivion Construction Set does not work on Vista x64.

I play on XP. my PC is over 4years old,soon I'm going tom invest in a new one.I'll order it without xp or vista,and install xp myself!...too many problems with vista.

Vista still has too much overhead that takes away too much in my gaming. Heck, I'd still be running these on Windows 95 if it was possible. Imagine how FAST your computer would be if you were running those old OSes!!

Vista will have(or already fulfilled) the same destiny as Windows ME. At the moment I will stick to WinXP even though it's not the best OS imo... If ATI support for Linux would be better, I'd probably say farewell windows, farewell forever

Amen to that. If everything I used my computer for (including games) was available (seemlessly) on Linux, I would switch in a New York minute.
