Default glxgears fps?

A couple of questions:

1) What sort of fps should I expect out of a Quadro4 9XGL on a Xeon 2.4G?

I am currently getting about 10,000 fps with one monitor and 5000 fps with TwinView.

2) Should I be getting such big difference in glxgears if I have TwinView enabled?

3) How can I toggle between TwinView and single monitor mode?

Ta.

Those are pretty decent scores.

Yes - you've increased the load on the card.

Currently, the only way to do it is to shut down X, modify your XF86Config file, and restart.

It might work to configure one of the MetaModes as "modetext, NULL". (Andy, do you have any ideas on that?) That would effectively shut off the other screen, but I don't know if that'll decrease the load on the card at all.

If you try it, then you can switch between MetaModes like you switch between normal modes already -- with Ctrl-Alt-keypadplus and Ctrl-Alt-keypadminus.

10000 ??? ouch!
I'm getting about 5000 fps with my Ti4400, running 1600x1200x32bpp on a dual Athlon MP 2260Mhz. I suppose the Quadro accelerates even more??

Good point. I don't remember if i've tried that, but it might work.

I believe it used to work (though the screen res stayed the same - it panned instead)

However, it doesnt work with the current drivers.

options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1

does these options really accelerate performance?

This is with a Quadro 980XGL RH 8.0
Dual 1.8Ghz Xeon


55382 frames in 5.0 seconds = 11076.400 FPS
55348 frames in 5.0 seconds = 11069.600 FPS
55823 frames in 5.0 seconds = 11164.600 FPS
55461 frames in 5.0 seconds = 11092.200 FPS
55884 frames in 5.0 seconds = 11176.800 FPS

What other lines do you recommend on the XF86Config file. I'm interested in the windows OGL settings conterpart of disabling vsync, Antialiasing, etc.

Thanks!

vsync and AA are disabled by default. They're controlled by the environment of the process that's using OpenGL -- if you have the __GL_FSAA_MODE environment variable set, for example, then it'll turn on one of the many FSAA modes that the driver can do. But only for programs started from within the shell that has the variable set.

FSAA and vsync, and probably others that I'm forgetting at the moment, are controlled this way; details are in the README (...somewhere).
