Updated and Optimized Ubuntu Free Graphics Drivers
pls use -O2 if you build intel graphics driver. it gives 20%performance boost in eg lightsmark 2008. radeon does not benefit much from that optimisations, but intel igps run some opengl parts on software. even sandybridge i guess. so pls use the standard mesa compiler options for building
Interesting. Since 7.12~git1107040958.39fecd I reverted to -O2. Let me know if it improves performance, or if there are other things slowing it (e.g. --enable-debug flag or glsl-to-tgsi branch).
You might want to add -fno-builtin-memcmp. Supposedly a big boost, but in my tests I saw no measurable difference. Could be more useful in an app swapping shaders more often.
I read the thread on mesa-dev about it (summary here), but I think it's better to wait a bit for an upstream solution rather than workaround it in my packages. I may add it in the following days if upstream doesn't address it.
pipe-video branch is now officially merged on mesa master. libg3dvl-mesa package with nouveau (XvMC only), r300 and r600 (XvMC + VDPAU) hw drivers is again available (softpipe drivers now also supported). See this post for instructions on using it.
Floating-point depth buffers.
glsl-to-tgsi branch no longer included (due to merge conflicts).
Also included x11proto-gl 1.4.14, needed by current mesa.
I just installed the latest packages from this repo but (for the first time) got the following errors. Could it be related to the latest 280.04 nvidia drivers from the bumblebee PPA, https://launchpad.net/~mj-casalogic/+archive/bumblebee/ ? Any ideas would be greatly appreciated.
