игра не запускается

I must add something.
Today, I've learnt than indeed, haigher fps reduces input delay, you were right, but only on the input delay. And I've denied what you've said because you've talked about frame rate too : "Have fun playing on 60 fps and insane input delay :)"
So basicly, I've said "60 FPS ? It's gonna be 60 fps anyway", and I was right on that.
BUT on the input lag, which I did not talk about, because I did not take this in consideration, yes, there is, indeed, a benefit at unlocking the FPS, even on a 60 Hz monitor.

btw, I still wonder if having maxed fps the GPU can display cannot lead to a "drop" of frame rates for very few times. In the cases the GPU is very stressed, running 120 fps could it cause drops to 30 when the GPU is stressed, where it would stay stable at 60, avoiding any stress of the GPU ?
🙄

A screen in 60 Hz can only display 60 frames per second. There is no way to display higher than 60 frames per second on a 60 Hz monitor.
What you're talking about is to remove the input lag caused by the v-sync, but now ending with tearing.
To remove tearing, you need to scale in game FPS to your monitor refresh rate, and this can be done in other ways than using v-sync, I let you seek for it.
Advice : Nvidia Inspector helps for that.

"Hertz(Hz) is the number of images displayed per second every time the monitor refreshes. This means that a 60Hz monitor will refresh images and return 60 images per second while a 120Hz monitor returns 120 images per second every time it refreshes."

Alright, answer my question :
what does a 60Hz monitor mean ?

Have fun playing on 60 fps and insane input delay :)

Yes, it did not change anything.
A 60 Hz monitor (which means than the monitor will have a frefresh rate of 60 times each second) will, by definition, only can display 60 frames per second. So, even if your graphic card actually calculates 300 fps, your screen will only can display you 60 fps.
This will create an effect named tearing, meaning than the screen will display a part of the next frame than your screen were not actually fast enough to display it entirely.
So, if you want to avoid tearing, I recommand the RTX graphic cards feature : G-Sync.
This has the same effect than V-sync, which is avoiding tearing (you know, the annoying line at the middle of your screen), but avoiding increasing the latency of your screen (the time between it is calculated by your computer, until it is displayed on your screen).

Joycity logic as usual gg

Are you actually stupid? Have u tried playing game like cs on 60 fps vs 300 on 60 hz?

if your screen is 60 Hz, it will not show up over 60 fps... so what's the point of unlocking your fps excepted creating tearing ?
