 |

hi guys. i'm a bit confused about this:
| Code: |
~ # uname -sr
Linux 3.7.10-gentoo
~ # glxinfo | grep -i opengl
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV635
OpenGL version string: 2.1 Mesa 9.0.1
OpenGL shading language version string: 1.30
OpenGL extensions:

isn't opengl 3 enabled by default in mesa 9.x ? if you need any additional information, just tell me. |

| You need R600_STREAMOUT=1 in /etc/env.d for it to work on Mesa 9.0. 9.1 and later enable that automatically. |

Did you solve this problem?
I have kind of the same problem here.

On gentoo TF2 is runing at around 20 or less fps.
On fedora there are no problems at all and everything runs fine.

I found me a solution for the OpenGL 3.1 problem.
Seems as if the mesa-9.2 ebuild is not feature complete.
After a lot (!!!!!!) of use google i finally found something in the phronix foums
So i messed around with the ebuild (as i am absolutely clueless how these things work .. did it quick and dirty and certainly wrong).
| Code: | | # vi /usr/portage/media-libs/mesa/mesa-9.2.0.ebuild |
and added
| Code: | src_configure() {...
if use egl; then
myconf+="
--enable-texture-float .... |
After that i did a
| Code: | | # ebuild /usr/portage/media-libs/mesa/mesa-9.2.0.ebuild digest |
to let portage think everything is in order, did an
Restarted x and as you can see:
| Code: | $ glxinfo | grep OpenGL
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CYPRESS
OpenGL core profile version string: 3.1 (Core Profile) Mesa 9.2.0
OpenGL core profile shading language version string: 1.40
OpenGL core profile context flags: (none)
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 9.2.0
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions: |
One step done.
So, why is TF2 on gentoo still performing so bad compared to running on fedora.
Any tip? |

Thanks a lot for the answer.
I will try it that way.
