   texture ripping o rotation
  hi, I've found when I rotate/move largish models that every so often textures flicker/rip.  I think this maybe due to refresh rate syncing? But am unsure. Can anone advise, is there some openGL command that says double buffer on monitor refresh? I'm using linux so double buffer with glXSwapBuffers.Thanks in advance :)   
  try the following first...glFinish();glXSwapBuffers();If it doesn't work, try the following command.wglSwapIntervalEXT(1);;Quote:Original post by ma_htytry the following first...glFinish();glXSwapBuffers();If it doesn't work, try the following command.wglSwapIntervalEXT(1);Never call glFinish. It kills paralellism between CPU and GPU. That function will wait for the GPU to finish it's work.wglSwapIntervalEXT is only available on Windows.I think that you can't enable vsync on the fly with *nix.   ;Quote:Original post by V-manNever call glFinish.

However, I guess there should be something equivalent on linux system.   ;Quote:Original post by ma_htyQuote:Original post by V-manNever call glFinish. It kills paralellism between CPU and GPU.

That's simply bad advice.There is this for *nix, but it's a SGI extensionhttp://www.opengl.org/registry/specs/SGI/swap_control.txtI have no experience with it so the OP will have to tell us if he succeeds with it.
