Cs2 doesnt feel smooth

I wonder if somebody knows how to make cs2 better maybe startup command. I have 180hz monitor and I can easily see the difference between 350 fps (bots on deathmatch)and 600 fps(bots disabled on deathmatch) 350 fps feels like 100hz and 600 fps feels just like my monitor max hz. I have everything optimized, no vsync freesync etc.

EDIT: I did 4 tests on mirage deathmatch (7bots) in the same exact location using rtss.
vulkan + 200 fps cap = 190 - 1% low 160 - 0.1% low (stable)
vulkan + 0 fps cap (350fps avg) = 120 - 1% low 100 - 0.1% low (stable)
d11 + 200 fps cap = 200 - 1% low 180 - 0.1% low (stable)
d11 + 0 fps cap (400fps avg) = 190 - 1% low 150 - 0.1% low (very big spiking - 50fps+/-)

From what I saw is that 1% lows and 0.1% have very big impact on gameplay and is the second main factor of smooth gameplay.

EDIT2:Alternative to rtss on amd gpu is radeon chill just set 2 sliders 10 fps above your monitor refresh rate. Using those methods are not perfect but it helps in case of smooth gameplay
