It happens because reflex requires 0.3ms to work.
So:
1000ms/360hz=2.777777777777778ms
2.78ms+0.3ms=3.08ms
1000ms/3.08ms=324hz - max possible refresh with reflex enabled.
I also wonder best possible scenario for CS2.
Based on this post I changed my RTSS frame cap from Async to NVIDIA reflex.
And I think I like the gameplay most with:
GSYNC ON + VSYNC NVCP ON + ULL NVCP ON + RTSS Frame limiter NVIDIA Reflex + VSYNC in game OFF + Reflex in game OFF + fullscreen
It could be just placebo, but I rly do not like in game settings of CS2. They feel strange.
Also I disabled DSC for my monitor, and without DSC max hz for HDMI2.1 10bit 2560x1440 is 330hz. I can alt+tab much faster.
