R600c/g benchmarks

[darkbasic]

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

<driconf>
  <device screen="0" driver="dri2">
    <application name="Default">
      <option name="vblank_mode" value="0"/>
    </application>

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

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.

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

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?

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

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

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

... I highly doubt that.

You're not watching a film and it's not a matter of reactions. The difference is very easy to feel. If you do not trust me, ask a professional gamer.

The difference between 24fps and 60fps is extremely noticable in an fps. If the physics and input are handled properly, everything above vertical refresh rate is not noticable, but there is a world of difference between 24fps and 60 fps.

But oscillations in fps are very distracting. If you get 30fps one second and 60 in another, it can throw you off. It's the difference between smooth and jerky, especially in a fast-paced game like Nexuiz.

ask a professional gamer.

Somebody with such limited brain power to actually believe that playing games is a profession is hardly qualified to answer technical questions.

Somebody payed by a sponsor to play a tournament *IS* a professional gamer and I personally know at least one people who had been already payed for a quake3 tournament.

Also, please keep your insults for yourself next time.
