Hardware 3d acceleration is enabled and works fine with glxgears but when I start a 3d sofware like google-earth it falls back into sofware rendering with the following error: *********************************WARN_ONCE********************************* File r300_render.c function r300Fallback line 486 Software fallback:ctx->Line.SmoothFlag *************************************************************************** visit this link http://digilander.libero.it/vezza for xorg.conf and xorg.0.log My system is a P4 3,0 Ghz 1,5Gb RAM with ATI RADEON 9800SE video card
Same here with Google Earth. Commenting out that line in r300_render.c enables acceleration.
By commenting out you have accelerated line drawing but not smooth line drawing even though with hight screen resolution and small linewidth you probably won't see the difference. Anyway the message you see doesn't mean it fallback fully in software rendering just that smooth line are drawed using software. So please don't report bug for that. This are functionality not yet implemented.
The current situation is that unpatched Mesa r300 provides horrible performance for an important application. Until the functionality is implemented, perhaps there should be a runtime config option to ignore the flag instead of falling back to software rendering?
