They're even worse than intel drivers.
In this list and in the last 2 years, a see more troubles related to the nvidia and intel drivers, than the Radeon. I do'nt remember in this list 1 problem related to the Radeon driver.
Because the problems I mention are related to high-complexity shaders. You seldom see that in linux (too few really sophisticated games). I write shaders, and I know many things I could write for nVidia I can't write for ATI. A while ago, it was loops. Loops killed ATI drivers while nVidia could handle them fine (and loops were part of the GLSL spec). Mesa has gotten way better since then, and open source AMD drivers are MESA-based AFAIK, so it may be different now. I just have no hardware to test with. In any case, both MESA and Catalyst break in a bad way when you invoke the API in unexpected (yet correct) ways. Mesa 7, for instance, segfaulted if you sent a vec4 for a float uniform. It shouldn't segfault, it should return an error code. Mesa 8 has that fixed, but has other issues I couldn't identify yet. It's not the kinds of bugs a graphical desktop runs into - only games. Not even blender makes such heavy use of shading capabilities. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
