nVidia GeForceGo 7300 performance issues

[musta ruhtinas]

I started this thread following various members' posts regarding glxgears performance. On my desktop I have an ATI X1600 Pro so I was quite aware of ATI's general limitations in linux when I bought my Toshiba A200-14D laptop. One of the requirements for it was to have a decent non-ati card, and Nvidia GeForce Go 7300 sounded more than just decent. Vista (which came preinstalled) runs just fine with Aero, yet I was expecting more out of Kubuntu now. I first installed nvidia-glx-new, then i thought to try envy (which i did, and the install went without issues), yet when I ran glxgears it showed just about 1500fps. I tried (out of curiosity) compiz-fusion and, though it itself ran smoothly, it did slow down many apps; glxgears would now show 150fps. I do not know whether glxgears is a good benchmarking utility, yet when one sees results that go towards 10000fps, one begins to wonder...
So basically what I would like to know is whether a score of 1500fps in glxgears is what I should expect running this video card in a typical, out-of-the-box install KDE install, without any customization, or there might be something I overlooked when setting the drivers up.

About testing graphics:

There is planetpenguin-racer

another 3D racing game featuring Tux, the Linux penguin

Using Ati 9600 XT

I get 100 - 120 fps (1680x1050, fglrx) with tux
40 - 50 fps (1680x1050, fglrx, Xgl, compiz fusion) with tux

glxgears: about 3500 (1680x1050, fglrx)
BUT
glxgears: about 7000 (1680x1050, fglrx, Xgl, compiz fusion)

fgl_glxgears doesn't work with Xgl:

glxinfo | grep rendering tells:
Xlib: extension "XFree86-DRI" missing on display ":1.0".
direct rendering: No

This is from Xgl

Frequently Asked Questions (FAQ)
Direct rendering does not work when running Xgl, but it does on Xorg. Why are OpenGL applications not accelerated?

Do not intermix hardware acceleration and direct rendering. OpenGL applications will be hardware accelerated on Xgl if the driver supports pBuffers or FBOs, like the nvidia and fglrx drivers do. Direct rendering on the other hand is impossible to implement at the moment, the necessary extensions for implementing that feature are not even specified yet, let alone being implemented.
Direct rendering implies hardware acceleration, but not the other way round. Direct rendering is a bit faster than indirect rendering, but indirect rendering is not as bad as it sounds.

I don't know how AIGLX works with direct rendering. Same problem ?

Thank you for the infos, especially about glxgears
I'll do some further reading on the matter...

This is my glxgears output

bob@kubuntubox1:~$ glxgears
88753 frames in 5.0 seconds = 17750.451 FPS
88190 frames in 5.0 seconds = 17637.972 FPS
91695 frames in 5.0 seconds = 18338.963 FPS
88718 frames in 5.0 seconds = 17743.578 FPS
89924 frames in 5.0 seconds = 17984.689 FPS
87350 frames in 5.0 seconds = 17469.973 FPS

Now, I wonder, if I install Compiz would that get down my FPS counting on Enemy Territory?

Re: nVidia GeForceGo 7300 performance issues

That's exactly what I was talking about!!! Never did I get even near that kind of score...
Ah well, I'll continue to study this when I got time for it.
Meanwhile if I could get my x1600 to work properly in gutsy >
