Allow Tearing doesn't work since November 23, 2023 update. #1391

Your system information

Issue description: The "Allow Tearing" option used to disable Vsync completely not only on external monitors but in the built-in display as well. This option now does nothing since the temporary workaround in the following update https://store.steampowered.com/news/app/1675200/view/3870342884095376976

Steps to reproduce:

  1. Turn on "allow tearing" during gameplay
  2. Turn off performance overlay (this being on prevented tearing regardless of setting)
  3. Disable Vsync in-game
  4. Tearing should be visible on the Deck's built-in screen (but not currently)

Can replicate with multiple games. No game tears with vsync disabled and allow tearning enabled

Does it really still not work, and Valve doesn't care?

Looks like it... I'm hoping for SteamOS 3.6 to fix this, hopefully...

Still broken in SteamOS 3.6.6 preview build, I'm afraid. :(

I don't understand the reasoning behind removing the functionality, but still keeping the completely useless/non-functional toggle in the menu.

As soon as Windows drivers are ready, I'm getting Windows 10 installed on this bad boy, I want to use lossless scaling frame generation and the dxgi flip presentation model that has infinitely less latency.

For OLED? Might never happen... It has been 7 months already.

does playing in desktop mode force Vsync to be disabled as is using x11?

I have set the desktop compositor to lowest latency and checked the setting to allow tearing artifacts. I do get tearing now, but only on desktop mode (and not in the built-in display) unfortunately.

Still broken in current 3.6 beta. I can also confirm that I am able to achieve full Vsync disable / tearing in desktop, but not in regular mode / gamescope. :( When trying to lower latency at all costs, this was a really useful toggle.

I can confirm, tearing is still not working in 3.5.19.
