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.
