Today I received my replacement Radeon 9700 Pro from ATI. It has yet to crash, even after running (for a test) Kyodai Mahjongg for 51 minutes. So it's probably safe to say that the previous card was faulty and my PC was okay. Hopefully I can now use it for programming. I'm also glad to announce that the DirectX 8 version of Kyodai Mahjongg is about 10% faster on the Radeon 9700 than the DirectX 7 version. Okay, not that it would matter much in such conditions (over 200 frames per second...), but it's still a nice surprise to me. Back to work now ! I have a beta version to finish for this week
