Striving for greatness

The life and times of a Gentoo developer and leader

[Gentoo] r300 driver and gaming

Update: See my newer post — UT2003 runs again, and Quake4 also runs. Overall, lots of textures are screwed up, however, so you get strange colors.

Just updated my Mesa to CVS HEAD from 6.4.1. I’m very pleased to see that UT2004 is fast enough to be playable now.

Doom3 does a lot better, although still can’t play it. It starts up now and gets through most of the intro, but it dies when it’s about to start the actual level.

Update: Apparently Doom3 works in multiplayer mode, which I can’t test because I have the demo version.

Ends with:

Quake4 doesn’t screw up my resolution anymore when attempting to start, although it still doesn’t start at all. Lots of missing extensions at startup time:

X..GL_ARB_texture_non_power_of_two not found
X..GL_EXT_shared_texture_palette not found

X..GL_ATI_fragment_shader not found

Ends with:
reloading gfx/guis/scrollbar_down.

One major and unfortunate regression: UT2003 no longer runs.

Xlib: extension "XiG-SUNDRY-NONSTANDARD" missing on display ":0.0".

Other games:
America’s Army is faster, but the colors are totally screwed up on many of the menu screens.

In another regression, Cube is now unplayably slow. Cube console output:

Legends plays great with both 6.4.1 and CVS HEAD, as does Enemy Territory.

Summary:

6.4.1 HEAD
UT2004 Too slow Works
Doom3 Doesn’t start at all, screws up resolution Can’t begin first mission
UT2003 Works Works
Quake4 Doesn’t start at all, screws up resolution Works
Quake3 Works Works
America’s Army Too slow Faster, colors weird
Enemy Territory Works Works
Cube Works Too slow
Legends Works Works

Kudos to everyone working on the r300 driver. Keep up the good work!
