[PyOpenGL-Users] Rendering performance under Xgl and compiz window manager

[Neal H. <nh...@do...>]

I have just installed SuSE 10.1, and have enabled the Xgl X
server and the compiz window manager.  Compared to my
previous environment on the same hardware, one of my 
applications is now noticeably more sluggish.  Its a simple app that
draws about 750 points and 1850 lines (modelling a building
frame).  When I drag the viewpoint around using the mouse,
what used to be a nice fast and smooth drag is now very jerky;
obviously the refresh rate is now much lower.

For what its worth, I now also get this message from the app:

> post:ardb> ./viewframe frame3
> 736 nodes,   1852 elements.
> freeglut (./viewframe): Unable to create direct context rendering for window 'Frame Viewer: frame3'
> This may hurt performance.

I'm using:
  freeglut-051110
  python-2.4.2
  PyOpenGL-2.0.2.01

Any ideas if this problem is solvable without going back to the standard
X server and kde window manager?  I just don't know where to begin.

Alltough, that wouldn't be too terrible.  The 3-D window manager is much
fun, but I'm not sure its that much of a gain, usability-wise.
