I’ve created a really nice UI with a simple controller layout that allows you to monitor the input from the steamdeck with a fancy imgui interface and also tested the performance a bit and its honestly pretty good. I managed to get around 8ms latency with 20ms spikes which is pretty good, also battery life is around 7 hours!!

It currently only works on linux as windows is trying so hard to make my life suck, so ill be adding windows support later on. It currently uses a custom driver with uinput that creates a generic virtual Xbox 360 controller that is automatically recognized by my pc and also by steam so thats great!

The process to make this work is pretty simple:

1. Add the steam deck side to steam as a non-steam game and make it use proton compatibility layer

2. Run the PC side

3. Run the steamdeck side

That’s it, the PC side recognizes the steamdeck instantly and there’s no setup required at all from that point on.

I would also like to add some sort of usb support but i think that will be a lot harder that im expecting :))
