It's no longer there. The only option now is to set your default proton version.

Hi I am having the same problem. Need to download some native linux game and steam play toggle is gone. In the individual games I can only choose proton, no Linux runtime.

Unfortunately steam has intentionally removed this feature. I discovered this when reading through the github issues for the linux client here:
https://github.com/ValveSoftware/steam-for-linux/issues/9957

I think we all need to make more noise there to get steam to see how bad of an idea this was. Here is there announcement of it and the terrible logic behind the decision:
https://steamhost.cn/steamcommunity_com/groups/SteamClientBeta/announcements/detail/4507632758953082943?snr=2___

Remove the UI toggle to disable Steam Play globally, correctly reflecting that Steam Play is always enabled on Linux. Steam Play was always partially active even when set to off in the UI as it is a requirement for Steam client operation.

The problem this causes is we can no longer run native linux versions of any game because proton is always enabled and forces even linux games to run the windows version with proton.

The Linux builds of the games I have installed still definitely work. What specific game is running the Windows build that shouldn't be?

Im not saying they dont work. I am saying steam is running the windows version via proton.

So Steam is running both the Linux and Windows build of your game in parallel? That's very strange.

What? No. Look.

When you press play its runs the windows version INSTEAD of the linux version BECAUSE steam play is enabled globally. When steam play is enabled globally it uses the windows version for all games via proton.

Which game is that happening for?

You dont have a clue how this works do you?

Which game is downloading and running the Windows version without being set to do so?

I'm typing this from my Debian Trixie laptop that I use for Steam game development right now. I want to figure out what's going on with the depots that's different for you than for me.

When "Enable Steam Play for all titles" is enabled it forces all game clients to use a windows version even if a linux version is available. Thats what that toggle did.

When steam removed that toggle and forced Steam Play to be enabled globally, by default, with no way to disable it, it forced all game clients to use proton regardless of a native linux client existing.

I typed this from arch btw.

Not only this but you can no longer sort your library by linux only games because Steam play causes all games to be seen as linux games.

Steam is even creating a prefix in compdata for these games with linux versions.

No, I'd had that enabled for years before they made it enabled by default. It just meant that you could play Windows-only games on Linux.

Games with a Linux build only switch to the Windows depots and run Proton if you set that specific game to use Proton.

The global toggle does not (or more precisely, did not) affect games that have a native Linux launch configuration.
