heh A friend of mine at my computerclub has Vista as well the buisness one and some games didn't even bootup propperly.
after playing Call of Duty 2 we switched to Fear Combat then Unreal Tournament Game Of The Year Edition 1999 and while switching to that game it had to be run under 98SE compabillity mode otherwise it wouldn't even boot, even my Voodoo 5 5500 PCI Macintosh couldn't be installed, it's that crappy with older hardware, imho Vista is totally useless for now on, I'm sticking with the best NT os'es out there Windows 2000 Professional + Rollup1 for Service Pack 4 and Windows XP Professional + Service Pack 2, they run fine on all systems with ATi as 3dfx cards as all 80 games I have here, Windows 2000 Professional is stillt he fastest one though, in most cases it's about 5% to 10% faster than XP pro in older games heh, just because it's alot lighter built, lesser eyecandy stuff and no crappy animations, Win2K Pro is still the best overall out there.
I rather wait till Servce Pack 2 is out for Vista, since it's packed with strange anomalies and runtime problems and most important of all I want 100% 3dfx glide support, as long that doesn't happen no Vista here hahah

it's more like Asta La Vista here
