steam-deck-windows-usermode-driver VS GlosSI

Can't you just run the beta Steam Big Picture on startup and run SWICD for controller support outside of Steam and get 90% of default SteamOS functionality?

You'll probably want to ask on r/WindowsOnDeck to get a better response, but I think there are two basic routes to try here. One is to try to force the Steam overlay to work with something like GloSSI or OSOL. The other is to use 3rd party drivers for the Deck's controls.

Or you can try SWICD or GlosSI

To get the controller working with Sunshine in Gaming Mode use this driver: https://github.com/mKenfenheuer/steam-deck-windows-usermode-driver

Steamdeck Windows Controller Driver

Hey I use this on battle net version on steamdeck and I was getting what you've been when I didn't use it

Try installing glossi on your host system and running it though that https://github.com/Alia5/GlosSI

GlosSI

If it’s a “non-steam” game, like Diablo IV, I use https://github.com/Alia5/GlosSI to act as the non-steam game for the launcher.

Download GlosSI installer from https://github.com/Alia5/GlosSI (when asked to during installation, install ViGEM driver as well)

Check out GloSI and it's Playnite extension, might be easier to assign input per game from Playnite

There are apps that act as middleware between Steam and these 3rd party launchers that can help. I use GlosSI.

You simply can't because there are no Drivers for it and Steam.exe is acting like the driver itself so that even projects like https://github.com/Alia5/GlosSI are piggybacking on Steam.exe's existence. You may try combining that GlosSI + SteamCMD (command line version) for a minimal impact on your system but you can't avoid installing Steam.

Now I assume you are running it through steam to make use of steam input. The workaround to run the launcher independently and still use steam input is to use glossi . Here’s a YouTube video on how to set it up: youtube .
