First off you should take this to !linux_gaming@lemmy.world like @tal@lemmy.today said
Can’t say I’ve ever tried to use “remote play together” with a game through proton. Does RPT work for you on other games? And what version of proton are you on?
The more Microsoft adds adware, surveys, and shitty requirements like tpm, the more people get finally fed up with Microsoft’s bullshit and finally switch to linux!
With the price being $200 you might as well spend 120 more to get a refurbished steam deck, install ps remote play on that then you have a handheld that can play ps, Xbox, and pc games on the go without an internet connection.
Odd last troubleshooting thing I can think of is to try plugging it into one of your front panel usbs since they are usually using a separate usb controller. Otherwise you might just have a defective unit
Likely just a usb bandwidth limit you are hitting, try unplugging other devices that arent in use, I had this issue with my rift cv1
Edit*
Also plug your rift directly into a usb 3.0 port on your motherboard, hubs even powered ones can cause issues with high bandwidth devices
