Re: PS5 Controller support on PC
SOLUTION - FOR PS5 CONTROLLER - WINDOWS 11 - ORIGIN
From all of the above tests, this is the one that has worked for me.
Completely close the Origin app (check it is closed in the task tray too)
Connect the PS5 controller via USB
Open Steam
Hit 'Steam' in the top left -> Settings -> Controller -> General Controller Settings
Tick "PlayStation Configuration Support"
Click on the Playstation 5 Controller under "Detected Controllers" at the bottom
Select Preferences
You can leave settings default here or adjust colours as you need. Then press "Submit" and close the settings boxes.
Add the 'non steam' game to your library
Games -> Add a non steam game to my library
Click browse and go to the install location (By Default in "C:\Program Files (x86)\Origin Games\Need for Speed Unbound\NeedForSpeedUnbound.exe")
Once added, run the game from here and enjoy!
Thanks to @fjusticia7 for the solution.
