glxgears showing <10 FPS with 2.2 ghz machine

WebGraphics · 01-09-2007, 08:35 AM

Direct rendering is on.

Specs:
CPU: AMD Athlon(tm) 64 Processor 3700+
Video Card: GeForce 6100/PCI/SSE2/3DNOW!
Driver Version: 2.1.0 NVIDIA 96.29 (current)

Yet when I run glxgears I get this:

52 frames in 5.1 seconds = 10.198 FPS
50 frames in 5.0 seconds = 9.999 FPS
50 frames in 5.0 seconds = 9.999 FPS
50 frames in 5.0 seconds = 9.960 FPS

So obviously something is wrong here. Any suggestions?

EDIT: I tried shrinking the glxgears window to the smallest possible size. This is what I got
49 frames in 5.1 seconds = 9.648 FPS
50 frames in 5.1 seconds = 9.865 FPS
50 frames in 5.0 seconds = 9.999 FPS
50 frames in 5.1 seconds = 9.842 FPS
50 frames in 5.0 seconds = 9.975 FPS
50 frames in 5.0 seconds = 9.999 FPS

So in other words shringking the window size had no effect at all.

i noticed Slackware-11 with Xorg-6.9 has noticeably slower 3D acceleration (on my machine) than Slackware-10.2 that uses Xorg-6.8.2

956 frames in 5.0 seconds = 191.200 FPS
956 frames in 5.0 seconds = 191.200 FPS
956 frames in 5.0 seconds = 191.200 FPS
956 frames in 5.0 seconds = 191.200 FPS
956 frames in 5.0 seconds = 191.200 FPS
956 frames in 5.0 seconds = 191.200 FPS

i am getting these speeds with just an old GeForce2 5500FX & a 17' CRT

i am sticking with Slackware10-2 because i was a little disappointed with Slackware-11 (hopefully Pat's next release will improve performance)

The most current driver version is 97.46

Code:

$ glxinfo | grep -i "opengl version"
OpenGL version string: 2.1.0 NVIDIA 97.46

I think there is no problem with your CPU but your video card is actually that slow. I have a CPU just like that one, 2.2 GHz 1Mb L2 cache San Diego core 90 nm, but I got a GeForce 7900GTX:

Code:

$ glxgears
93266 frames in 5.0 seconds = 18653.163 FPS
94775 frames in 5.0 seconds = 18954.864 FPS
94772 frames in 5.0 seconds = 18954.386 FPS
94665 frames in 5.0 seconds = 18932.913 FPS
94711 frames in 5.0 seconds = 18942.173 FPS
94769 frames in 5.0 seconds = 18953.789 FPS
94749 frames in 5.0 seconds = 18949.621 FPS
94755 frames in 5.0 seconds = 18951.000 FPS
94759 frames in 5.0 seconds = 18951.641 FPS
94738 frames in 5.0 seconds = 18947.558 FPS

I know that glxgears is not a proper benchmarking tool, but the difference in performance should be pretty obvious.

Also, with ATI cards it has been showing slow too.

As long as your video seems to beworking, and

Code:

glxinfo | grep direct

shows dri working, don't worry about it.

If it isn't working, check my dri post (link in my sig)

Mostly, it seems the newer drivers just don't like glxgears....lol

Not sure what your problem is, but I'm sure you can't blame it on Slack 11. I've just fresh installed Slack 11 on my server, which is powered by an AMD K6, running at 450MHz, with 256Meg of memory. The video card is a "generic" GeForce2 MX/MX 400, with 64Meg, that cost me less than $10 at Frys. Running the NVidia 96.31 driver (my card isn't supported by 97.46), I get a GLXGears frame rate of 640 FPS.

heers.

Well I seem to have resolved the issue, only problem is that I'm not sure exactly how I did it. I installed the latest nvidia drivers and the FPS went up quite a bit...

Only the problem is not (or was not) that simple because the FPS used to be high, then it went very low (not sure why), and now it is back to normal... to anyone experiencing a similar problem I would reccomend just installing the nvidia drivers for linux, if you're using nvidia card.

For the record this is what I get now:

4317 frames in 5.0 seconds = 863.214 FPS
4319 frames in 5.0 seconds = 863.699 FPS
4306 frames in 5.0 seconds = 861.129 FPS
4313 frames in 5.0 seconds = 862.483 FPS

raska has some really high framerates, i wonder if he was running the glxgear window in full screen, when i first open glxgears it defaults to a small window and i get those super high framerates too, maximize the window and see what you get

raska · 01-09-2007, 11:31 PM

Logically maximizing the window gives me less frames, though don't how you get them higher instead

Code:

$ glxgears
75200 frames in 5.0 seconds = 15039.847 FPS
90682 frames in 5.0 seconds = 18136.225 FPS
91133 frames in 5.0 seconds = 18226.574 FPS
92007 frames in 5.0 seconds = 18401.289 FPS
91906 frames in 5.0 seconds = 18381.163 FPS
24104 frames in 5.0 seconds = 4820.764 FPS  <<--- maximized window from here
24122 frames in 5.0 seconds = 4824.292 FPS
24107 frames in 5.0 seconds = 4821.357 FPS
24108 frames in 5.0 seconds = 4821.551 FPS

i raska, thanks, i guess my hardware is getting old, this PC only has a 1.4 gig AMD CPU and 1 gig RAM,

i could build a new PC with the latest & greatest but i rather save the cash for a rainy day...

@Okie

Hardware isn't your problem.

You will get low numbers (3-digit) if composite is on. I get 472 FPS (fullscreen) with my 6800 GS, but with composite off I know it will be a 4 or even 5 digit number.
