High refresh rate monitors not behaving normally

Post by dystopia11111 » 19 Mar 2025, 21:38

Hello,

If my fps gets higher than my monitor's refresh rate my game gets really jittery like its on 60hz. The only thing that helps is gsync + vsync + low latency mode.

The only fps lock that works without gsync is through RTSS, but then there is a lot of screen tearing. I am planning to buy a zowie dyac monitor (i want to use dyac so no gsync).

I cant make my screen smooth but not tear at the same time with low latency. I have tried 2 different monitors and gpus and reinstalled windows like 3 times. Cant seem to find the core of the problem. 400 fps on a 180hz screen shouldn't be a problem no? Even if i have gsync on it is terrible, while it does not tear, its like 60hz and i have to use vsync. Nothing seems to help

It would help if you could list your hardware (PC & peripherals) and software stack (windows version & drivers, game in question & game-specific settings)

This might be of use to you:

There could be a few issues going on, I'll list a few I can think of with the limited information you've provided:
1.) You could have instabilities in your hardware components (CPU, RAM or mobo)
2.) DRAMless SSD causing stuttering
3.) PSU could be insufficient to power your PC or has high voltage ripple.
4.) No mention of GPU, the respective driver & settings used, which can heavily impact your experience.
Reflex is a must if you play CS2 at 1440p, considering it's heavily GPU-liimted nowadays.
5.) Wireless mouse having interference from other wireless sources around it
6.) Not using a frame rate limit which is a multiple of the refresh rate of your display, use https://boringboredom.github.io/tools/fpscapcalculator & watch the video I've linked above
Do keep in mind that CS2 has a ridiculously bad in-game frame limiter implementation in terms of frame pacing, using RTSS front-edge sync will give you the best frame times at the cost of 2 extra frames of added latency (if 360fps cap — +5,55ms of added latency), other solutions are 1 frame of added input latency.
7.) Improperly tuned Windows settings (disabling Windows Defender, Windows Updates etc.)

Hope this helps.

I have exactly the same problem and it is with me for years, no matter what refresh rate - 144,165,170,120 they all feel the same, and at none of them you can see any smoothness,

my rig
H570 TUF GAMING
i5 11400F
RTX 3070 Phantom Gaming
32GB Patriot BLACK Viper 3600MHZ
and most importantly monitor: MSI G274QPF

please if anyone has any fix apart from robotic bull **** responses like: "cHeCk YoUr ReFrEsH rAtE at WiNdOwS SeTtInGs" send it here or at my steam profile, thanks.

It's normal to see jitter/tearing if things are not in sync, making the effective sample rate feel as reduced. Frame rate must be in perfect sync with Refresh rate for ideal motion. That's why gsync and vsync helps. Also it's not just frames, mice have their sample/polling rate too. It's worth checking that as well.

Vsync perfectly caps the frame rate to monitor's refresh rate as long as frame rate is above the input refresh rate, + it adds lag if so.
Gsync synchronizes monitor's refresh rate to frame rate as long as frame rate is bellow the input refresh rate.

Meaning u need one or the other, or both. For now try Gsync + Vsync and make sure to cap frame rate ~5% bellow refresh rate to stay within the Gsync range + bellow Vsync threshold.
