Triple buffering question.

[MonsterAb1]

Does triple buffering help or cause input lag?

What's the difference between double and triple buffering and should it be used on a 144hz monitor even if you don't get 144 fps in game?

Input lag also becomes more of an issue with vsync enabled. This is because the artificial delay introduced increases the difference between when something actually happened (when the frame was drawn) and when it gets displayed on screen. Input lag always exists (it is impossible to instantaneously draw what is currently happening to the screen), but the trick is to minimize it.

Our options with double buffering are a choice between possible visual problems like tearing without vsync and an artificial delay that can negatively effect both performance and can increase input lag with vsync enabled. But not to worry, there is an option that combines the best of both worlds with no sacrifice in quality or actual performance. That option is triple buffering.

Triple buffering will introduce more input lag with VSync in theory.

If you have GSync/Freesync with 144 Hz, you should never use triple buffering, just double (vsync on). With double buffering you are locked to your monitor's refresh rate. So, for 144 Hz, you typically have 144 fps, 72 (=144/2) fps, 48 fps (=144/3), 36 fps (=144/4) and so on.
With triple buffering you have the same fps as without vsync. But you need more video ram und you have more input lag. "Triple Buffering" is from its three image buffers. One which is actually shown on your monitor, one which is already computed and shown when your monitor has the next refresh (144 times per seconds in your case), and one which is actually computed.
Triple Buffering has nothing to do with OpenGL. It's just the technique of three buffers to keep the FPS as high as without vsync.

Ok. Thanks for the replies. Going to try out remote hacking as that should give me an idea on how much lag there is with it on.
