I'm using xorg-x11 fyi. I've also had this problem with XFree86. Does anyone know how to speed this up?

what *exactly* is your problem?

the output is exactly what you want. It lists the properties of different visuals the X-Display is offering and lists which OpenGL-properties can be used, etc.etc.etc....

You are using direct rendering, so everything is sweet!
use glxgears to actually measure the fps you get.

Have fun*

Sorry I should have stated my problem a little bit clearer. Everything is working as you can tell. But it seems like direct rendering is slow. When I move my mouse around sometimes there is a little delay in movement. And the screensaver isn't smooth. How would I go about speeding this up?

Edit: This is the output of glxgears



Code:
1772 frames in 5.0 seconds = 354.400 FPS
2004 frames in 5.0 seconds = 400.800 FPS
1916 frames in 5.0 seconds = 383.200 FPS
1959 frames in 5.0 seconds = 391.800 FPS
1912 frames in 5.0 seconds = 382.400 FPS
1906 frames in 5.0 seconds = 381.200 FPS
1934 frames in 5.0 seconds = 386.800 FPS
1945 frames in 5.0 seconds = 389.000 FPS
1912 frames in 5.0 seconds = 382.400 FPS
1920 frames in 5.0 seconds = 384.000 FPS



And the weird thing is that when I have the glxgears window behind the terminal it's faster....

Code:
2706 frames in 5.0 seconds = 541.200 FPS
2752 frames in 5.0 seconds = 550.400 FPS
2693 frames in 5.0 seconds = 538.600 FPS
2750 frames in 5.0 seconds = 550.000 FPS
2770 frames in 5.0 seconds = 554.000 FPS
2713 frames in 5.0 seconds = 542.600 FPS
2752 frames in 5.0 seconds = 550.400 FPS
2783 frames in 5.0 seconds = 556.600 FPS
2727 frames in 5.0 seconds = 545.400 FPS
2696 frames in 5.0 seconds = 539.200 FPS

It's fine. For a rage 128, that is about what you can expect in terms of FPS. I know what you mean about the gears not appearing to move very fast. I have the same thing on my radeon 9000. The reason is that the gears spin so fast they appear not to spin, to spin slowly, or to spin in the wrong direction. It's an FPS mind-trick.

A better benchmark for FPS would be to emerge armagetron, fire it up and check your FPS in that. You should get about 20 FPS in an 800x600 window.
