These are typically only about half (maybe slightly better) as fast as the 128bit cards (enabling hyperz and color tiling should help some, you need xorg 6.9 for both features, and hyperz needs to be manually enabled). The games you mentioned should still be playable though even with the 64bit cards. If this is a pci radeon 9250, that could also explain the slow performance. In theory, this should not really cause a performance loss, but for some yet unknown reason the pci radeon rv250 based cards are a LOT slower than the agp ones.

But this is strange since thay have a much simpler graphics as q3 has. If q3 has a decent framerate these "home-made" games should work also. My card is an AGP one, I don´t know whether it´s a 64-bit one or not. Do you have any explanation for that? </pre> </blockquote> <pre wrap=""> In Torcs disable the rear-view mirror. It uses copies from framebuffer to texture which isn't accelerated ATM AFAIK. Or use the latest Torcs version (1.2.4) which includes a fix that improves the performance of the rear-view mirror a lot compared to 1.2.3. Neverball can be slow if you have many coins in a level and set the geometry detail to "high". Also if you have reflections enabled and use 16bpp color depth you hit software fallbacks due to the lack of a hardware stencil buffer. Try using 24bpp color depth or disable reflections and if that doesn't help reduce the geometry detail. Regards, Felix </pre> </blockquote> OK, thanks for your help :) If this is not a bug and the performance is just not that good I can live with that. Is the "radeon" driver still maintained and improved? I mean that some features aren´t accelerated ATM, and I also heard that it uses just AGP 1x because higher modes are buggy. regards Michael Stather </body> </html>
