Thanks for quick answers. Is RTSS much better than Nvidia driver cap, or it's the same, but more precise?

It's the same, but it's not suitable for this because it doesn't offer a way to enter fractional values. You need at least 0.01FPS granularity, and the driver limiter doesn't provide a way to do that, even though it's just as accurate as RTSS otherwise.

I'm going to experiment with QFT. What is the best value to set in CRU 60.000, 59.950 or 59.920?

It doesn't matter, but usually you want something only very slightly above 60 (like 60.01.) In this case, you don't need RTSS for the cap because you can just use the nvidia driver limiter with a cap of 60. However, the end result might not be what you actually entered. It might take a few tries where you check the true refresh rate, and if it's too high, you try lowering it a bit.

Btw, if you could get rid of the VRR flicker, that would be way better than doing any of this. What is the VRR range of your monitor? Sometimes you can fix flicker by changing the VRR range in CRU. For example try a range of 66-165 or 75-165 and see if that helps get rid of it.

QFT for 60Hz and 120Hz.

My VRR range is 48-165. I already tried 65,70, etc for low range, but didn't help much. This is 34" ultrawide QD-Oled freesync, and flickering is unavoidable on OLEDs. I have the same flickering on LG 42" C2 as well.
I play a lot of fighting games, where you have loading screens every few minutes, and framerate drops to 30fps, or sometimes I enable steam overlay to message someone and again flickers like crazy.
In Tekken 8 it is great example on character select screen when 3d models load in the game stutters and flickering is insane. With vsync it's ok because nothing is really moving on the screen.
edit:
I just tested 1/2, 1/3 and even 1/4 vsync with RTSS cap -0.01. It works absolutely perfect!
Please correct me if I'm wrong, but if for example I run the game at max 164.900Hz, 1/3 vsync, 54.956fps in RTSS, when the game will drop frames below the cap, judder should be less visible than if I would run it at 55Hz?

I was thinking that lower will be better for games that have in-game 60fps cap that can't be disabled. I guess 119.920Hz with 59.95fps should be perfect.
Anybody have input lag measurements with this method? I would like to know the difference vs standard vsync on/off.

The low latency vsync cap requires the cap to be lower than your refresh rate. So if you cap to 60 with the nvidia driver's limiter, refresh rate should be at least 60.01. If you use RTSS, then it doesn't matter obviously. I only mentioned it in case you want to use Nvidia's limiter.

I think I'm just going to use RTSS cap for more precision. For example my max true frequency is 164.900Hz, so if I like to use 1/3 vsync for some heavy games like Cyberpunk it will require cap at 54.956fps.
I'm using RTSS with Afterburner anyways for undervolting my 2080ti, and for OSD.
