Frame generation will add a lot more lag than vsync.

Good to know. Though to be honest, probably because it's 1. a turn-based game, 2. one I'm playing on a wireless controller, I'm not noticing it.
So I guess even V-Sync is fine for this game. But it's this were a more latency-sensitive game, it might've been annoying.
What should I have done then?
Would exclusive full screen have been fine?
Would exclusive full screen have been fine?
Probably. I think Proton puts everything into a window either way.
Wait, so that means FreeSync would NOT have worked, since it doesn't now?
I'm not sure if its Bazzite, or nVidia, or what, but any time I turn frame gen on it makes my games run like shit. This goes for every game and I have two PCs it does it on.
I also cant seem to get adaptive sync to work properly. I am on the gnome version, maybe thats related? Most of my games boot with a black screen when its turned on. V sync seems to work fine and did for me in Clair obscur too.
- 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.
