My old display was "4k" 3840x2160 resolution, with 60 Hz.
Games with vsync had a stable 60 FPS, i wanted more.
I dissabled vsnyc and had up to 300 FPS.

What i have been reading and hearing everywhere is, a display with 60 refresh rate cannot show more than 60 framesperseccond.
This might be true, or not.

The 300 FPS compared to the 60 FPS was an insane noticable diffrence for me.
The game was smooth to play in a way thats not possible with 60 Hz.


How can i notice the diffrence from 60 to 300 FPS, if my display was only 60hz?
Fact is 300 fps feels WAY smoother to play than 60, i dont understand tho why is that? cause my display cant show more than 60 pictures.


My new monitor is 165 Hz with 2k resolution. 2560x1440.
Im using it with 165 FPS max option in the nvidia control panel.
Most games wont go over 165 FPS anyways because gsync is on,
but some games could go to 300 FPS.

2560x1440 with 165 Hz 165 Fps
VS
2560x1440 with 165 Hz 300 Fps

Humans can notice the diffrence?
 
Solution
Without vsync frames will be displayed at a 3.3 interval even if the display is not ready for it causing tearing,a 60Hz display can display 60 full frames per second at 16ms, partial frames are a different matter.
V-Sync is a separate topic, anyone playing reaction based games should not using V-Sync due to the additional latency/lag it introduces. Agree when FPS is 300 they will be sent at 3.3ms intervals, they won’t be displayed at 3.3ms intervals as the monitor ignores 4 out of 5 frames that don’t get displayed. However this is the point, the maximum latency between a frame being sent and received by the monitor is 3.3 when running 300fps. If 60fps the maximum latency would be 16.3. This is why esports gamers run frame rates...
