R600c/g benchmarks

Yes, but if you want to seriously play an online fps the framerate must never fall below the 60 fps barrier.

Why? Because you think that you can see, process, and react to something in 1/60th of a second?

... I highly doubt that.

How exactly is that just "acceptable"? You're breaking 24, so you're fine.

I just wish this were for the 4000 and 5000 series and not just the 3000. Or am I mistaken?

A 4870 should perform much, much better as far as I know. For 5000 series maybe it's a bit early.

Note that nexuiz is finally (barely) playable at low quality! In fact lowest framerate is 36 fps and medium framerate is 53 fps, which is acceptable.

Ah but you know that the game really is built around high fps. Those improvements are the ones I'm glad to see. I just wish this were for the 4000 and 5000 series and not just the 3000. Or am I mistaken?

My card is a Radeon HD 3870. I used today's snapshot of: mesa, libdrm, xf86-video-intel, drm-radeon-testing.

To disable vsync I applied this patch

diff --git a/src/radeon_dri2.c b/src/radeon_dri2.c

                          0, 0, drawable->width, drawable->height, 0, 0);

and I put this is /etc/drirc

Nexuiz: "demo1" time demo
I couldn't do any benchmark with R600g because it was too much slow and with too much artifacts to bench (color tiling was disabled). I had to restart X.

These are the results:

Openarena Very High quality @2560x1600

----- R600c + color tiling
----------- 92.3 fps

----- R600c w/o color tiling
----------- 69.7 fps


Openarena Very High quality +flare +bloom +8x aniso @2560x1600

----- R600c + color tiling
----------- 67.6 fps


Nexuiz Low quality @2560x1600

----- R600c + color tiling
----------- 53.0 fps, min/avg/max: 36 55 88

----- R600c w/o color tiling
----------- 51.2 fps, min/avg/max: 36 53 81


Nexuiz Medium quality @2560x1600

----- R600c + color tiling
----------- 31.4 fps, min/avg/max: 15 35 80
