checking 3D acceleration of graphics
To check whether 3D acceleration is supported by the current graphics drivers, use glxinfo:
Where acceleration is working, the 'direct rendering' parameter will have the value 'Yes', followed by details about which features are supported.
Code:
apt-get install mesa-utils glxinfo

That's not always the case:
$ glxinfo | grep direct
direct rendering: Yes
$ glxgears
1733 frames in 5.0 seconds = 346.452 FPS
1733 frames in 5.0 seconds = 346.516 FPS
1733 frames in 5.0 seconds = 346.525 FPS
^C
$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_fragment_program,
$
~350 fps is entirely too slow for this to be true hardware acceleration, especially for an ATI HD 3450.Posted 05-31-2011 at 04:26 PM by rocket357

Good point. One has to check whether the 3D rendering is being done by software or hardware.
