G-Sync + V-Sync input lag confusion
Posted: 29 Dec 2018, 21:02
I recently re-read the G-Sync review and technology explanation, but I was still confused regarding input lag addition/increase when comparing G+Sync + V-Sync (double buffering) and V-Sync-only (double-buffering) with G-Sync disabled entirely.
AFAIK, in fullscreen exclusive mode, at 60fps/hz, enabling V-Sync (double buffering) adds 16ms of input lag and at 120fps/hz, it adds about 8ms. Does the same apply to enabling V-Sync on G-Sync-capable displays with G-Sync enabled?
I thought that G-Sync, by itself (with V-Sync disabled), barely adds any input lag or doesn't add any at all andwhen V-Sync is added to G-Sync, then input lag is increase by some 1-2ms, not 16-8ms at 60-120hz...
If V-Sync does add that much input lag, even with G-Sync, then Borderless Windowed mode is still superior for input lag, even though there a slight decrease in FPS.
