I have two new (compared to my Win95) boxes (OK, they're both over 3 years old but whatever). One runs WinXP SP3 and the other one has WinVista SP2.
The XP box has an onboard VIA/S3G UniChrome IGP (64 MB) graphics card, 2GB of RAM and a AMD Athlon XP (2.08GhZ) processor.
The Vista has a Radeon X300/X550 Series (128 MB) graphics card(sorry, I don't know the exact model number; I bought it used to replace a fried GeForce 7300), 2GB of RAM and an Intel Core 2 Duo (1.8GhZ) processor.
The interesting thing is, on the XP; the 3D Text screensaver runs very slowly and the iTunes visualizer can only get to 10FPS max, but Empty Clip runs at 50-60 FPS.
On the Vista, the screensavers run fast, the iTunes visualizer gets 20-25FPS, but Empty Clip only gets 5FPS max!
Does anybody know why one box can get great FPS but the other one doesn't and vice versa?
Both cards support DX9.
