FreeSync not working in Clair Obscur? (lemmy.ca)

In using Bazzite DX with KDE and a 9070 XT. I'm playing Clair Obscur in borderless windowed mode because that's the only way it'll allow me to turn on frame generation.

I was getting quite a bit of distracting tearing. But adaptive sync is on "always".

The tearing disappeared when I unchecked the option to allow tearing in full screen windows, but if I understand correctly, that's V-sync, and it increases latency, right?

It's a turn-based RPG so latency probably not the end of the world, and I honestly haven't noticed the difference so far, but it kinda feels like it's not ideal. Was there something else I should've done?

  • Is Variable Refresh Rate enabled in your system settings for that monitor? If it's turned off, no game settings will change that.
  • Second, my understanding is that VRR only works for Fullscreen games. Borderless probably won't work.
  • Third, V-sync does not work with VRR. You are correct to turn that off.

I'm no expert, so hopefully that helps!

There's no option named variable refresh rate. But there is one called Adaptive sync. It's set to Always.

If VRR can't work in borderless windowed mode, I guess I'll have to give up on it for this game. Because I get distracting frame drops without Frame Gen. A bit unfortunate I'd have performance compromises with my brand new graphics card, but I heard this is normal for UE5 games.

I did some extra checking, and it sounds like for Linux, there isn't really a true exclusive fullscreen, but some games will behave differently depending on which mode you choose (because of how they've been coded). If you're getting bad tearing in borderless but not fullscreen, it may be one of those finicky cases.

It's strange that you can't turn on frame gen in fullscreen, though. Maybe it's a bug that you should report.

I haven't had an occasion to try it, but CachyOS's Proton supposedly has FSR 4 support. Maybe try that version...? Details here:

Huh. Thanks for the tip. I'll give it a try the next time I play.
