On a Medion notebook with Intel 945 Express graphics chipset it streaks like mad under Vista, beta 2 is worse than beta 1. tried 16/32 bit have not got updated drivers yet (lunch first then google)
Ah just noticed it is SW rendering so unlikely to ever work?
OK
(medion laptop is model WIM 2160. Other numbers on it ar MD96290 and 1257)
Ran the update driver from the Vista device manager, after a long long time scouring the web it loaded a driver update and now the screensaver runs correctly even though still on software.
