First all, thank you for this forum.
It seems that Vsync in RetroArch is mandatory if you want to use Gsync, as without it, the latter does not activate or work (source: [link](https://www.libretro.com/index.php/upco … ync-users/)).
NVIDIA panel configuration.
If I don’t limit the FPS in RetroArch, for example, if I leave it at 141fps to play OpenLara at more than 120fps, it causes stuttering in 60fps games.
By limiting the FPS to 59.9 using MSI Afterburner, I manage to achieve a smooth experience, meaning perfect framerate without stuttering.
RetroArch configuration: Vsync on (mandatory to enable Gsync).
In other words, if I limit it to 59.9, I fix most games, but it affects Dosbox Pure and OpenLara, where the former reaches 72fps and the latter reaches 1440fps. In OpenLara, it’s not as noticeable, but in Dosbox, it ruins pinball games.
I’m not sure if someone can help me, but I understood that VRR (gsync or freesync) precisely limits the frames to what the game requires, and I realize that if I leave the FPS unlimited at 59.9, it’s as if VRR (variable refresh rate) doesn’t work.
I’m having stuttering issues on Windows 10. My system specs are an AMD 5800X with 64GB of RAM, Nvidia 4070ti, and NVMe Gen4. The monitor is a Gigabyte that supports up to 270Hz with options for 120Hz, 165Hz, 200Hz, 240Hz, and 270Hz.
Currently, I have the monitor set at 165Hz. Using Custom Resolution Utility, I can force other refresh rate configurations, but the key is that RetroArch has issues when I don’t limit the FPS to 59.9. If I don’t use RivaTuner and let RetroArch detect up to 165Hz = 162fps (always limiting 3 or 4 fps for optimal Gsync), there seem to be problems.
The issue is that even with Gsync enabled, if a game has 60fps and I run RetroArch, it doesn’t seem to work properly. The GPU fluctuates a lot, and stuttering occurs.
Can you recommend any configurations?
What am I doing wrong?"
All of this is with a freshly formatted Windows 10, no background programs, everything optimized.
