If you've got a Quest and an AMD card, use AMD's built-in hardware accelerated VR streaming. 

Truly wireless Rift S emulation.
Lower overhead than using virtual desktop.
Hardware acceleration.
Built in to your drivers.

For me the performance has been absolutely perfect, I just wish there were more options in the driver for it.

To use it open the radeon settings thing, go to the gear, to go "General" and enable "SteamVR Integration". You'll need to sideload the APK here https://github.com/GPUOpen-LibrariesAndSDKs/Radeon-ReLive-VR and you're basically done. Run that APK and it should just werk.
