144 hz and 300fps

[pwn]

Tell me you found the answer to your question.
My monitor refresh rate is 144 Hz (2411p), my average FPS is 300-350 FPS.
  Do I need to set 143 fps lock to get the minimum delay?

I heard something about the frame buffer, that it is better to have a limited number of frames in it

Depends on your setup...

G-SYNC/FreeSync:
-3 FPS limit (or under) below max refresh rate for lowest (sync-induced) input lag

Standalone V-SYNC:
-0.xx demical-based FPS limit below max refresh rate via RTSS for lowest (sync-induced) input lag

Standalone V-SYNC OFF:
Highest FPS above refresh rate as possible (typically) for lowest input lag

Yeah typically an unlocked frame rate and no Vsync of any type is the way to go. Locking it at 144 FPS for instance would give you around 6ms of latency or so between frames I think, which does indeed make a difference. Even with a 60hz monitor you're still going to benefit from the higher fps, you just won't physically SEE them all but you will absolutely feel them.

In fact the only time I'd even recommend capping the FPS is if you're getting massive spikes all the time as this causes larger latency changes which will mess with your accuracy and at this point I'd cap it right around the minimum FPS.
