I just got the dock for it, I am a little concerned I’ll notice any performance issues more when hooked up to a large screen.

I’ve been using it predominantly docked and the performance is quite decent. A few tips:

• You can use the streaming function if you have a decent PC.
• Set device resolution to the resolution you want the game to be playing in. E.g. 1080p or 4k, then set the native in game resolution to something lower. Next, set your scaling filter to FSR instead of Linear. This will scale up the in game resolution to device resolution without sacrificing the internal memory and heating up the hardware.
• Make sure you set your TV to game mode to reduce input lag for controllers.
