cpu spiking

[Orm Finnendahl]

Hi,

 using cl-opengl with cl-glut I'm getting 100% cpu usage when
eliminating the (glut:post-redisplay) from the #'glut:idle method
(after doing that nothing is redrawn of course).

When including (glut:post-redisplay) back into the idle routine, cpu
load is reduced, presumable due to the calculations on the gpu (the
more intense, the more the cpu load is reduced). Does anyone have an
idea how I could debug this? Is this glut related and would it promise
better results with sdl2?

Any help is appreciated!
