The issue comes down to how the device interacts with your computer. Just like the original version, the new Steam Controller has no native Windows drivers. This means the hardware relies entirely on the Steam app to function properly. If you do not have the game running via Valve’s storefront app, your shiny new gamepad turns into a useless piece of plastic.
Gamers Nexus also reported this and there are a lot of other news outlets also covering this. It is kinda the same as with the steam deck where I noticed that the inputs just don’t work until steam is launched. I really don’t like that I have to have Steam running for this controller to work. I don’t know if it is a dealbreaker for me, yet, but it really put a damper on my enthusiasm about it
I’ve done that too. Also tried the ds5 but it needs a 3rd party app to work for almost everything.
What it really comes down to, for me, is whether I’ll use the gyro, grip sense, and track pads.
If those aren’t for you, there are a bunch of tmr controllers for different sized budgets out there. A lot of them even work with switch/2 and that’s nice bc the 1st party controllers are the worst.
