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! -- Orm
