Why The Radeon Gallium3D Performance Is Down

[Hamish Wilson]

Kudos to both Michael and Marek.

chrisr, it is reverted in this branch, which I will push soon:
git://people.freedesktop.org/~mareko/mesa radeon-perf-fix
It fixes the performance regression in Nexuiz and hopefully even the bug you reported.

Thanks, Marek. This bug affects both R600 and R300 and so I'm really hoping that it will be fixed before Mesa 7.12 is released.

Sidicas, the performance improvement is unrelated to the regression in r300g. The regression is caused by a commit that's merely a cleanup.

Michael, thanks for doing this. The commit "winsys/radeon: move GEM domains out of the drivers into winsys" will be reverted, fixing Nexuiz.
The commit "r300g: implement fences using dummy relocations" won't be reverted. It properly implements glFinish(), which is used by openarena to eliminate the input lag. It's important for playability of the game.

Unfortunately 93f4e3cb6c1ca303ee1f5c2a2491a8eff33f2633 regress 0 A.D.: fps go from ~30 to ~20.

Forgeot to add that I am using kernel 2.6.39.3 and my card info:

r300: DRM version: 2.9.0, Name: ATI RV530, ID: 0x71c5, GB: 1, Z: 2
r300: GART size: 509 MB, VRAM size: 256 MB
r300: AA compression RAM: YES, Z compression RAM: YES, HiZ RAM: YES

In that case, why don't you test whether the first commit, which it partially reverted, improved 0 A.D. performance?

Offtopic: If only my HD3200 worked with mesa trunk... bug 43405: Evergreen support broke it
--there's a fix, but noone's tested on Evergreen. (guess I'll test if git head works on HD3200 later today, though there's very little chance of it).

Nope. Still snow.
With the patch it works nicely, though.

i tested the newest oilrush+the radeon driver and i got 7fps-

what is the best opensource driver result for a card? please only results with working hdmi audio.

it is possible to get 30fps with an opensource driver? sure 1900x1200 resulution is used and max game settings is a must have
