I see. So it sounds like you have the MBP set to the non-retina setting then passed to quest via immersed? (ie if you look at the laptop screen IRL everything is very small) But in the headset it functions almost as though it was nearly a 50" 4k TV. So presumably has the macOS text issues but worth it otherwise.
And the mouse latency is fine wirelessly?
(Sorry, I don't love the retina word but I haven't found a substitute since high DPI resolves to so many other things.)
