Even though I've got "use openGL Vsync" selected in the front end settings, the frontend only ever uses USleep with busy wait timing.
I suspect that I may be able to improve things by changing my Xorg.conf file or my nvidia settings, but I'm not really sure what works when using dvi, as opposed to tv out.
Any clarification of all this would be welcome, I did find a post (below) on the ATRPMS site that mentions the different timing methods, but I've been unable to find out what are the pros and cons of the various types

"I compiled Myth last night and the OpenGL sync works great on both of my NVidia cards. I didn't have time to try the ATI card. The first sync method to be available is what will be used: 1. NVidia sync (4363 driver only) 2. DRM sync (not sure what this is) 3. OpenGL sync (but has to be enabled in settings.pro, not sure if it works on other cards, will test tonight) 4. RTC sync 5. Busy Wait So basically if it fails on one of the sync methods it will try the next one. Busy Wait should work on all systems. I will test more tonight. Axel Thimm wrote: > Thanks, sounds reasonable.
