Seth Hillbrand a210fd570f Set VSYNC to adaptive (if available) 
Swap syncs can limit the redraw rate as the screen waits for previously
issued syncs.  Setting this to -1 allows for adaptive swapping
(resorting to unsynced if it falls behind) if it is supported by the
card but will fall back to unsynced (0) if the adaptive is not
supported.
