GloSC VS UWPHook

For GTA V (I have the "Epic Store" version), I just added the "Rockstar Launcher" as a "Non-steam game" and it worked with no issues. I had to use GloSC for Genshin Impact and other games.

I had an issue where my PC viewed the backbone as keyboard inputs, so I had to use this GitHub project and it works flawlessly now. https://github.com/Alia5/GloSC I just do a blank one, not linked to any games, and launch it on my PC via Steam before I plan on streaming on my phone.

GloSC

You could try this https://github.com/csutorasa/XOutput that seems to work like xc360 but works with UWP, or maybe https://alia5.github.io/GloSC/, to open UWP apps trough steam and use the steam controler interface to assign the buttons.

I think you might need this to get it to work https://alia5.github.io/GloSC/

I mean the SC is not tied to Steam. Lots of games I play with the SC I start as a non-steam game from Steam and it works fine. Also https://alia5.github.io/GloSC/

I just setup Steam link for the first time, and was disappointed to find that when I launched an Origin game, my controller would default to it's Desktop Mode inputs. Same thing happened for an Epic game. I've seen people suggest various third party software (OSOL, GloSC), but what I did was remap Desktop Mode so that instead of RT being click, LT right click, LS the mouse cusor, etc...... RT was RT, LT was LT, LS was LS, A was A, B was B, and so on.

Edit: here's UWPHook to link gamepass games to steam https://github.com/BrianLima/UWPHook

Use UWP HOOK to allow you to add windows store uwp games to steam as a non steam game.

I used this https://github.com/BrianLima/UWPHook

It's usually difficult because Microsoft UWP DRM on them so you needing tools like UWPHook & other workarounds that have 50% success rate at most. There are rare Gamepass games that don't have UWP so it won't be a problem for them.

You could try using https://github.com/BrianLima/UWPHook this program and testing it. I really doubt it'll work, the VR tag is just a categorisation thing and so it shows up on the HMD page. It doesn't actually trigger any VR capabilities.

Microsoft : This is worst with all from above and you need https://github.com/BrianLima/UWPHook to be able to play against Microsoft DRM.

Another option that could potentially work is to use UWPHook to add your Xbox Game-Pass games to Steam and then simply use Steam Link to stream these games.

There's a nifty little utility called UWP Hook (https://github.com/BrianLima/UWPHook) that scans your Windows Apps and lets you pick them from a drop-down to add to Steam, but there have been a rare couple games that absolutely refuse to show up on the list so i made a bit of a convoluted extra step to gain access privileges to the gamepass install folder and add them from there when needed.
