And again: you need 144.008Hz. 144.002 is not enough. So you should raise it in CRU until you get 144.008 in the test.

Or, use the fractional FPS limit of RTSS, using the LimitDenominator setting. In that case you leave the monitor at 144Hz and use a 143.992FPS limit.


So I finally get home and here is my tests (if I did everything correctly):

If I raise the cap on CRU to 144.015Hz I get this values:

It's good enough? Unfortunately if I change to 144.014Hz it goes all way down to 144.002Hz... Not sure why.

So, this is my test now with the RTSS cap to 144:

An incredible flat line! But it seems as good as before if you check the other screenshots, same 6.9ms value and flat line.

The ingame limiter seems better to, but a little above (7.2ms~) and a little jitttery. But RTSS seems better overall!

This is just mindblowing! Vsync + Blur Reduction + low input lag! I honestly can't believe yet!

The only way to be sure whether RTSS or the in-game limiter gives you the least latency, is to actually measure it. Unfortunately, no one has done that yet. I just suspect that it's RTSS that gives less latency here, since it's able to prevent the game from reaching the vsync limit. The in-game limiter is jittery, and that means the game hits the vsync limit often.

But until someone measures this, it's just conjecture on my part.

Btw, you can get a "second opinion" on the real Hz of the monitor here:

I hope someone with the right gear test when possible! But seems very interesting so far!

Didn't know you guys already had a test here! It seems the same 144.011Hz value (when it is stable after a couple of seconds).

144.011Hz is perfectly fine, btw. Even 144.02Hz is still OK. The time between frame skips is still large. (The higher the difference between cap and refresh gets, the more frequent frame skips will occur.)

Frame skips start to actually become noticeable once you get to a 0.05 difference or so. This depends on the game; you will notice them easier in a racing game that has constant smooth movement, for example.

Ty very much for all your patience! I'll try to fine tune here!

Step 2 different method: Using CRU

Instead of using a fractional RTSS frame rate limit, you can instead continue using the default frame cap, but instead modify your monitor's refresh rate slightly. You can do that using CRU:

https://www.monitortests.com/forum/Thre ... tility-CRU

For example, if you want to cap to 60FPS, modify your 60Hz mode to 60.007Hz. For 120FPS, modify your refresh rate to 120.007Hz.

The downside to using CRU for this is that you need to re-apply your edits every time you upgrade your GPU drivers.
Is this still accurate? My CRU still seems to keep the custom resolution, even after I upgraded my Nvidia drivers...

Have you rebooted? It loses the settings after a reboot.

Which isn't a problem. You can export all your current tweaks in CRU into a .bin file, and then import it again after the upgrade.

Just rebooted, the custom resolutions (240.010 it says, but shows up as 240.011-240.012 in vsynctester.com as well as the custom 182Hz one I added, which isn't included with the monitor) are still there in CRU utility. o_O
