Really ODD issue

[Diekan]

So... I get the ATI drivers installed in my Ubuntu install.

Got Doom 3 installed and working as well... but I noticed it was choppy... so I run glxgears to get an idea of my FPS.

First...

xxxxxx@Neo:~$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600
OpenGL version string: 2.0.6334 (8.34.8)

So, looks like the drivers are good... it shows ATI and not MESA, which is a good thing.

I ran glxgears for a quick look and got:

xxxxxx@Neo:~$ glxgears
26620 frames in 5.0 seconds = 5323.895 FPS
42590 frames in 5.0 seconds = 8517.956 FPS
42589 frames in 5.0 seconds = 8517.666 FPS
42575 frames in 5.0 seconds = 8514.809 FPS
42485 frames in 5.0 seconds = 8496.885 FPS

Ok, looks good... but then I close the terminal window and reopen it... run glxgears again and was surprised to find:

xxxxxx@Neo:~$ glxgears
1370 frames in 5.0 seconds = 273.872 FPS
1321 frames in 5.0 seconds = 264.197 FPS
1305 frames in 5.0 seconds = 260.997 FPS

K... what the fuck? How do I lose some 8300FPS? Nothing was done between closing the terminal on the first run and the second run.

Ok... I did notice that when I run glxgears right after a reboot I get good FPS's -- it's when I run glxgears during computer use (after the initial check) that I find FPS of 200... which is terrible.

However, even with an FPS of 200... Doom 3 still loads and plays. Choppy yes, but not unplayable per say.

Um, your frames per second numbers look really screwy. Choppy video is below 30 fps. Ultra-high-end systems run modern games with the bells and whistles turned on at no more than 90ish. Even old crappy games they won't do more than a couple hundred. 5000 frames per second is a ridiculous number.

Look at Guru3D's review of the 8800 series. http://www.guru3d.com/article/Videocards/391/19/ (the whole thing is like 30 pages long, so I went straight to the results with FEAR) Even at only 1024x768, a 8800 GTX was only getting 150ish FPS. Something's wrong with your results.

LOL, 8500 FPS? At that point you're seeing the word "H-e-l-l-o" coming out of your mouth as you say it and time travel becomes possible.

Was there a difference between the size of the terminal windows you ran glxgears in. The 8000+ numbers from glxgears is not weird its normal, glxgears gives incredibly high results especially when rendering in a very small windows. If you run it in full screen you will get much lower results.
