Well, beryl runs a little better here with new nvidia driver, some tweeks to the Beryl settings and of course some tweeks to the nvidia driver itself:
Code:
Status:          Enabled
Driver:          AGPGART
AGP Rate:        8x
Fast Writes:     Enabled
SBA:             Enabled
Glxgears is still only up to just below 260 FPS with all that. Some 460 with the Metacity windowmanager. I also managed to crash the DVB (my digital TV driver) after I set Fast Writes, something that has never happened before, so yes, things seem a little less stable with it enabled. I haven't switched it off yet though...

Beryl is very heavy by the looks of it, maybe the new version will be more efficient.

I don't think you can blame Beryl. I'm getting around 1975 fps with a 128MB GeForce FX 5600XT. Something else is wrong.

Correction: 1200 fps in Beryl, the 1975 fps is in Metacity. Doh.

I'm getting about 1600 fps on my 7800GS, with my fully loaded system. One of these days I'm going to shut just about everything down and try it just to see what I could be getting.

Changing options in beryl can have a really huge impact on glxgears fps.

Yes, absolutely. Glxgears is a very poor tool to use as a benchmark, it will drop fps dramatically as the system is loaded.

Monsm: Do you have all the advanced beryl setting set to "Auto'? In beryl-settings, General Options, Main: 'Detect Refresh' should be unchecked, 'Refresh Rate' should be manually set to your monitor refresh rate, 'Sync to Vblank' should be unchecked. That seems to provide the best performance.

I saw another post somewhere about those advanced beryl settings, I might give that another try switching them back to auto. They are on specifics now (GLX binding, force AIGLX, etc). I also deleted my .beryl directory on my user, to reset all the settings. It seemed to help a bit, no particular effect on glxgear rating though.

As you would expect it spin a bit easier without transparency on. I'll have another look when I'm back home from work this afternoon. My ratings are nowhere near yours, so yes, there is something wrong somewhere.

If everything else fails I might rebuild the whole system using the latest Gentoo DVD I downloaded last night...

Hi guys, still there?

I have, after some time, now solved this performance problem.

Check this:
Code:
16488 frames in 5.0 seconds = 3297.537 FPS
16226 frames in 5.0 seconds = 3245.189 FPS
16316 frames in 5.0 seconds = 3262.797 FPS
16353 frames in 5.0 seconds = 3270.093 FPS
16114 frames in 5.0 seconds = 3222.730 FPS
16088 frames in 5.0 seconds = 3217.478 FPS
16269 frames in 5.0 seconds = 3253.774 FPS
15926 frames in 5.0 seconds = 3185.170 FPS
16198 frames in 5.0 seconds = 3238.765 FPS
16259 frames in 5.0 seconds = 3251.732 FPS
15885 frames in 5.0 seconds = 3176.907 FPS
16264 frames in 5.0 seconds = 3252.720 FPS
16364 frames in 5.0 seconds = 3272.772 FPS
Some improvement from the 1250 average I had with my old Beryl setup.
I made sure I was running just 1 bash terminal and firefox in addition to glxgears as before.

Have a look here:

So what have I done?
1. Rebuilt my PC to Gentoo (which compiles everything specifically for your CPU and selected optimizations).
2. Installed Compiz-Fusion.
