I tried it on mine and my ps5 controller doesn’t add latency, and my wired USB c controller doesn’t either, I used the pro max and got caught of guard by how little heat it had for the first few min, but takes 5-10m for it to get so hot you worry about your battery, but with a special controller that has a fan and additional battery it could work great IMO.

It’s stunning and shocking on a phone honestly but it’s nothing but a tech demo IMO, not very pleasant to play, I’d rather just use cloud gaming instead
