If I render a blank screen @ 60FPS & 1024x640 & no clearing, 33 % cpu is used. 1024x620 it's 7% -  a very significant non-linear difference.  Both tests are running in windows mode on a GLJPanel and have no display/init/resize code - the bare minimum.  Anybody can explain this and recommend a fix?

Regards,

Monty

Avoid using GLJPanel if possible, GLCanvas is a bit faster where sometimes hardware acceleration works bad with GLJPanel.
