I just installed Vista 5384 ( http://www.tweaksforgeeks.com/windows-vista/2006/06/vista-beta-5384-install-error-code-80070241
) and after the fun I had detailed in that little link I got it working.
I like the HyperSpace screensaver made by whoever writes the "Really Slick" screensavers. http://www.reallyslick.com

They use OpenGL to render their prettyness. In XP they run splendidly, however, in Vista it runs like complete ass. I did download the very latest drivers for my nVidia GeForce 6800 and I've got a gig of RAM as well as an Athlon 64 3000+ so I'm thinking that my computer should be sufficient. (Not the fastest thing ever, but decent)
I hear that OpenGL is now "layered" over Direct3D which would explain the performance issue, but I think that's only for actual desktop applications or whatnot (stuff run in a window). The full-screen OpenGL you'd think would be left alone since it takes control of the display adapter.
Anybody else have issues with it? Or is something just up with my machine?
