64-bit Catalyst for Windows XP for AMD64
ATI have finally released the much awaited 64-bit Catalyst drivers for 64-bit Windows XP for AMD64. I did some benchmarks with them (on ATI Radeon 9600 XT) and they have about the same performance as Catalyst 4.5 under 32-bit Windows XP. There is one big problem with them though. The 32-bit OpenGL driver doesn't work at all and crashes immediately when you try to start any 32-bit OpenGL application. I hope they fix this soon and that they release updated drivers ASAP. What we are still waiting for are the 64-bit Linux drivers. Let's hope ATI is working hard on them right now.
