Need Explanation of Vsync Controls in nVidia D3D tab

[Sporko]

Well I guess I don't need one but I'd like one.

Actually it's the "render no more than x frames ahead" that I don't understand. It appears to be connected to Vsync because if I set Vsync to "Always Off", it automatically changes to "... 0 frames ahead."

Also, what does the "Auto-Select" setting do?

Thanks for any help.

That "render no more than x frames ahead" setting is pretty buggy at the moment and doesn't really do anything.

Also, what does the "Auto-Select" setting do?

That allows games to control the status of vsync.
