Hi, I'm Felix!
I bought the DualSense PS5 controller some time ago. But now I have a problem that is really annoying! So… I boot up my PC and then I usually play a few rounds of Rocket League on Epic Games (my controller reacts and goes). Then I start Wallpaper Engine (including Steam) and mostly play some games on Steam. Then I feel like RL again, so I start it and my controller no longer reacts… So my guess is that as soon as I start Steam my controller is somehow different or something. The thing was a week ago everything was still normal so it didn't matter whether I played RL or Phasmophobia…
Oh, if I restart my PC everything works again…
I really need help!
That's because the steam has a kind of controller mode and I guess that your controller connects to steam as long as steam is open (in your case permanently because of the wallpaper engine) I don't know myself very well because the only game I have with a controller games jump force is.
