 			Double-buffering may give you the lowest lag/latency but if V-Sync is on and the system can't render at 60 fps, the framerate will go down in multiples of it (e.g. 30 fps, 15, 7.5, etc.). Triple buffering gives you higher framerate (specially if the system can't reach a constant 60 fps) at the cost of up to 1 frame of latency, with [constant DisplayServer.VSYNC_ENABLED] (FIFO).
 			Use double-buffering with [constant DisplayServer.VSYNC_ENABLED]. Triple-buffering is a must if you plan on using [constant DisplayServer.VSYNC_MAILBOX] mode.
