I bet the reason we don’t have it yet starts with N and ends with Vidia

There are some modders experimenting with eGPUs on the Deck, but it’s really impractical. The Deck USB-C connector isn’t powerful enough to handle an external GPU and the OS doesn’t support it.

Valve would need to release new hardware for it to be feasible.

We all know there won’t be a Deck 3. So I hope they take their time on making the second one perfect.
