Package: python-opengl
Version: 2.0.1.09.dfsg.1-0.2
--- Please enter the report below this line. ---
I also noticed heavy performance problems with python-opengl 3.
I tried 3.0.0~b3-1 from sid and 3.0.0~b5-1 from experimental.
With the attached test-script I get about 5.7 frames per second.
Then I built and installed the etch package 2.0.1.09.dfsg.1-0.2
and reached about 100 frames per second.
(The script draws 300 rectangles and calculates the average fps
during 5 seconds)
There is also a similar bugreport for Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/pyopengl/+bug/135736
They also report that version 2.0.1.09 is running fine.
