Hmmm, while this does stop it from locking, the underlying problem seems to be the gpu taking up a ton of time.
I've tested 2.2 and 1.2 glsl_mandelbrot.osg (1.2 was fine last I used it), now they both take up alot of gpu time (>80ms per frame), so I'm not sure what could be causing this. Installed the latest drivers for my card, but it didn't help, not sure what else could've changed that would cause this. May just reinstall the OS and start fresh if I can't figure out whats going on, any ideas would be appreciated though. --- Alberto Luaces <[EMAIL PROTECTED]> wrote: > El Sunday 07 October 2007 03:09:55 idontgot aname > escribió: > > It seems that as I zoom in/out, the framerate > stays > > locked at a certain range until it can't handle it > > anymore. 60fps zoomed out, down to 30fps, down to > > 20/15/10 etc. and the gpu time goes up because of > > this. > > > > Does anyone know why the framerate would stay > fixed at > > those ranges? > > Hi, > > this is a matter of synchronization with the screen > refresh.
