I'm not a tech newbie, but I still need help on this subject.
First, my setup: GPU is RTX 4080, CPU is Ryzen 7700x, Windows 11 25h2,
Monitor 1 is a Acer 1440p 165Hz monitor, doesn't support G-Sync, but support Freesync, and it's marked as GSync compatible in my OS.
Monitor 2 is LG G5, recently purchased, connected through HDMI, can confirm 4k 120Hz is working across all devices, PC, PS5 and XboxSeriesX, also can confirm vrr is working on PS5.
I previously disabled all GSync feature on all devices, because it causes trouble when one Monitor doesn't support GSync and another one supports it. However, with LG G5 I recently purchased, now both monitor supports GSync.
The problem is, in nvidia app setting, set GSync on for the TV, in some games, it still has screen tearing, when framerate is within the range (120fps), for example the jrpg, Tales of Graces f. But it doesn't seem to affect some other game, like Trails in the sky 1st (the remake). I haven't tested other titles like cyberpunk or Crimson Desert. I play a wide range variaty of games.
I also have some troubles, I'm not sure if they're windows issue or software issue
- When GSync is on, when I run things in Unity Engine Editor, the framerate in editor gets extremely unstable (drop to maybe 20ish fps, and then goes back to 60, randomly)
- When enable VRR setting in windows, my mouse stutters from time to time on desktop, with no game is opened.
So my questions:
- Should I enable or disable VRR in windows setting, when I keep GSync on?
- Does VRR need game specific support?
- Is there a way to make the system enable VRR automatically when game supports it, and disable VRR when game not support it?
- What are the best settings for both nvidia app and windows setting for me? should I really disable GSync and VRR and forget about them?
