How should glxgears look?

[kurisu]

I run glxgears and it is very jerky. The frame rates it produces vary quite wildly. My OpenGL screensavers run smoothly however. What is going wrong?

The frame rates it produces vary quite wildly.

How wildly -- can you let it run until you've got 6 or 8 lines of output, and then post them here?

Hi,

From memory (at work at the moment), it begins with about 500fps and then gets up to around 1200fps. You'd think such a frame rate would be smooth but it ain't!. I'll post back with actual output when I get home. Thanks.

Re: How should glxgears look?

Sounds a little puny -- it needs to run a few thousand fps to do a decent job on things that move. Probably your graphics chip can do better than that -- post your chip make and model, your motherboard and CPU, the output of

lspci

, and we'll see what it takes to get your glxgears up to snuff.

Hi,

I have an AMD64 3700+ (San Diego) CPU on an Asus A8R32-MVP Deluxe board. My video card runs on a ATI Radeon X300SE chip. Here is the result of lspci and then glxgears:

243320 frames in 5.0 seconds = 48663.980 FPS

Holy smokes -- no wonder the X server shut off! I've never seen such a number ...

Well, your bad luck is that I have experience with ATI closely approaching zero. Your good luck, maybe, is that the Envy script installer available here: http://albertomilone.com/nvidia_scripts1.html purports to handle ATI cards as well as Nvidia cards, which is what I have. So, I would recommend you review the instructions, download and install Envy, and run it to do the driver installation. On my system, it doesn't always want to run in GUI mode, so in a console you can type

sudo envy -t

and it will take care of business in text mode.

Good luck -- hope this helps.

Re: How should glxgears look?

Yeah I thought that was ridiculously high.. but I quit glxgears rather than X dying! I've noticed kded using about 50% of my CPU all the time for a while now.. just happened to Google it and found that knemo might be causing the problem. Got rid of knemo and hey presto no more CPU hogging. I ran glxgears again and got much more stability. Still a bit low but my card is a cheapie:

chris@chris-desktop:~$ glxgears
Xlib: extension "XFree86-DRI" missing on display ":1.0".
3988 frames in 5.1 seconds = 789.016 FPS

4320 frames in 5.1 seconds = 843.861 FPS
4320 frames in 5.1 seconds = 844.024 FPS
4320 frames in 5.1 seconds = 843.970 FPS
4320 frames in 5.1 seconds = 843.740 FPS
4320 frames in 5.1 seconds = 843.620 FPS
4254 frames in 5.0 seconds = 843.710 FPS
4320 frames in 5.1 seconds = 842.980 FPS
4196 frames in 5.0 seconds = 834.979 FPS
3240 frames in 5.8 seconds = 554.264 FPS

I'll try envy and see what happens. Up to now I've just used fglrx via the restricted manager.

Thanks,
K
