Originally I had it WiFi both ways. I had input lag, so I restarted my Google WiFi and it was fine for a day then went back to being bad. I restarted it a second time and it was still bad so I went wired.

I guess it could be different for your setup.

Just played the whole of Alan Wake Remastered. My PS5 is wired, steam deck is WiFi. Works great. Originally ps5 was on WiFi it was unplayable with input lag, now it’s perfect
