Way to force off a games v-sync?

[Platsys]

So normally on windows if a game has no v-sync options and it's forced on you could use either nvidia or Amd's driver settings to force a game to disable its v-sync, is there any way to do this on steam deck/linux?

Did you find a way?

Heh, me neither. Imo it's a massive bummer that you're getting vsync forced on the deck. I'm also surprised that there's barely any information about the topic, eventhough the steam deck has been around for some time. I mean how can people enjoy playing with delay?

I guess I'll have to nuke the entire os and replace it with windows. SInce I'm mainly playing cod and some other bnet games like overwatch, I'll most likely have to do that anyways.

I think we're thinking of different things. I do agree we should have a way to disable valves global adaptive sync, but I was talking the v-sync that's forced on by the game, like with the dark souls games

v-sync is forced on in any game on the deck. You cannot disable it, regardless what your settings are.

there is a difference between steam os v-sync and a games v-sync.
If you turn off a games V-sync the framerate is allowed to be whatever the steam decks power will allow, not limited to 30 or 60fps.
whereas a lot of games version of v-sync WILL limit you to multiples of your screens refresh rate.

In my case some games usage of v-sync causes even more input lag and thats what I was trying fix, not valves os level v-sync.

also if your trying to eliminate lag on the deck I recommend using steams launch options to limit the framerate without using the games v-sync or using valves frame limiters.

you can use this one for the majority of games: "DXVK_FRAME_RATE=60 %command%"

And this one for games that don't like it (usually dx12 games like elden ring):

"MANGOHUD=1 MANGOHUD_CONFIG=fps_limit=60,no_display %command%"

Gotcha.

Thanks a lot for these suggestions, unfortunately they don't seem to disable the os vsync. The commands work though, the fps are limited, but the latency is still there. there's also no single bit of screen tearing at all :(

The latency makes it impossible to play competetive games like overwatch.

Two more things you can try, you could cap the game to like, 120fps through launch options and disable steams limiter. if your able to run it around that framerate it will feel noticeably more responsive.
personally when I played hollow knight and rogue legacy 2 on steam deck at 60fps I thought they felt really off, after capping to 120fps they felt near perfect, at the expense of battery, heat and fan noise of course.

the other thing you might try if your desperate is following one of the first two comments on this reddit post, I haven't looked into it but its the only thing I can find about disabling the os v-sync

Noooo. If that was the case, how come the decks FSR DOES NOT WORK unless vsync is enabled with Fullscreen. Played a demo game just now, no in game vsync ATM and I am unable to utilize decks fsr bc there is no vsync

Have you looked at the date when this was posted? Yes, vsync can be toggled off now.

This is untrue as steam deck is literally a handheld PC, also you can enable or disable screen tearing
