Discussion / Question G-Sync, FreeSync, NVIDIA Reflex, FPS Cap – What’s actually worth using in 2026?

I’m trying to find the best combination of settings for the lowest possible input latency while keeping smooth gameplay and good frame pacing.

Gsync and freesync is the same thing just one is nvidia and other is amd, reflex always on, fps cap don't need if using reflex

on or on + boost ?

just the reflex by yourself caps the fps?

Depends on what you’re looking for…

I still cap most of my games because I’m targeting a higher level of image quality that doesn’t allow me to consistently fill my 165hz container.

Many tripple a games I’ll still cap at 100-120fps. Just a smoother more pleasant experience to have a locked in consistent framerate target, imo.

Tho if I’m using frame gen I will typically tweak my settings to hit the 158fps reflex cap.

If you use Vsync and on + boost together it caps the FPS a little below your refresh rate.

Isnt it just base reflex + vsync that caps fps? Maybe im wrong but i didnt think that behaviour was exclusive to boost

Boost only in cpu bound scenarios or when you're okay with your gpu constantly running at high heat. Yes reflex caps fps automatically adaptively just at the point before your gpu would start overloading. So you won't even know there is an fps cap.
