I wouldn't consider it a bug at all period. Performance is something that can be improved upon in software, not something broken that requires fixing. While you may or may not see performance improvements or degradation from changing kernels, that is a complete side issue. Xft rendered fonts are not accelerated, and until they are, there is a performance bottleneck created when using applications that use Xft. >I changed Xfree console programs fonts to 'miscfixed bold 15'(the old 10x20) and >speed is normal. At other X programs It doesn't mind to me. You've changed fonts to a fixed font, and the speed is now normal. That is in tune with what I am saying above, as a lot of the codepaths used by antialiased scaleable fonts are _not_ used in misc fixed. Thus a performance increase. Has nothing to do with the kernel whatsoever. >And a question: Is AGPMode an automatic setting? The AGPMode setting either should not ever be used by the end user, or it *MUST* match the AGP mode that your BIOS has programmed the AGP chipset to at boot time. If you set AGPMode randomly, then you are likely to experience system lockups and other problems. Also, AGPMode has no effect on 2D graphics performance. -- Mike A.
