Microstutter in games without Vsync and with infinite FPS.
Microstutter in games without Vsync and with infinite FPS.
Hello everyone. I want to apologize ahead of time for my English. I came seeking advice because I'm really stressed and unsure of what to do. This is my third computer in five years, and I've encountered the same issue on all of them. The issue is that when games run with vsync off and an unlimited FPS setting—like in CS2 or Dota2—I get 180-250 FPS without any drops below 144 FPS (on a 144Hz monitor). However, if I play at 20 FPS, the game feels very jittery, as seen in this video at 0:05 and 0.35 seconds.

I've tried everything possible—new cables, new keyboard, new monitors, updated graphics drivers, sound settings, reinstalling Windows, and checking forums. Still nothing works. The only part I haven't changed in five years is the mouse. Could it be that the problem lies with the mouse? My polling rate is set to 1000Hz, the mouse is a Zowie EC2-A, and the DPI is 1600. Nvidia settings are optimized for performance, and my PC is configured for maximum speed.
PC specifications:
i5-9600K
MSI GTX 1080
16GB DDR4
Keyboard: Hyperx Alloy Origins
Mouse: Zowie EC2-A
Monitor: Acer Predator XB241H with built-in Gsync chip
The only way the games run smoothly is when Gsync and Vsync are both enabled, and FPS is capped at 137. But in that case, I experience a terrible input delay, which is frustrating, especially against others who have no such issues. Anyone else have faced this problem? How did they resolve it? Thanks.
You may find the earlier piece on fast sync versus vSync and latency useful.
Stuttering usually stems from a brief shortage of a vital CPU resource, often the processor itself.
Boosting CPU capability can be achieved by overclocking your 9600K chip if you're using a Z motherboard.
Consider a CPU upgrade, especially one that improves single-thread speed.
A corresponding motherboard replacement might also be necessary.
Fps over refresh often causes a shaky visual but doesn’t cause a hard skip. How’s your CPU usage looking, particularly for core #0? If it’s at full capacity, that’s likely the reason and you may need to adjust how many FPS your CPU can handle without stutters. Have you considered restricting FPS without Vsync? Gsync only controls the range of FPS, not the actual limit, and should automatically disable when out of range—this should eliminate lag, though results may vary. Make sure your mouse settings in the game are set to raw input mode. Try setting the FPS limit to 143 with Gsync enabled only.
