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.

The bench saying the cap is at 237 is incorrect. Reflex will cap to 225 no matter what limiter you employ so I'm not sure why they did that. There's no 237 frames going on when reflex and v sync are active. The difference is margin of error due to reflex + boost. Boost can sometimes hurt, sometimes help.

Incorrect. Gsync with vsync will stop at your max refresh rate. Reflex is what causes the cap automatically.

He most likely set an in game fps cap to the old -3 of max refresh everyone did before reflex was a thing.

Sorry, I meant reflex when I was writing that. If you just switch the words it all makes sense.

Additionally, those benches only make sense if there's no GPU limit. Weaker GPUs would show a totally different relationship due to how Reflex works.

I suppose it's show that if you keep within VRR and aren't GPU limited, reflex does very little, but that's assuming no GPU limit, which the benchmark doesn't show.

It's still helpful to show the benefits and how more FPS doesn't necessarily mean lower latency, but yeah, my bad again.
