MacOS just doesn't really play well with non-retina text anymore. I think windows/linux probably has clearer text at lower PPDs.
I am guessing I have about 40 PPD. I still have a sliver of space on each side where I see part of my support screens (vertical 1080P on each side). It has a 110 degree horizontal FOV.
My main screen is driven by the MacBook Pro's native resolution (3456x2160). Immersed can create 4k virtual screens, but I don't really see an improvement, the Quest's panels are the limiting factor.
Not crisp like retina, but the size makes up for it. In very rare cases I just lean right up to the screens (they are 3 feet from me). As the focal point is somewhere 4-5 feet away, you can have your face right against the screen to see tiny detail.
Also the fast refresh (I have mine set to 120Hz) matters. I tried my work's Vision Pro. Yes, more crisp graphics. But it gave me motion sickness, there is a slight motion blur, the pixels don't seem to refresh fast enough. The Quest is rock solid, never felt unwell using it.
I really don't even notice it is not retina.
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.)
One other thing that is an unexpected bonus. It rains where I live. A lot. And when it is grey and dim, I can sit in a "sunny office". In fact, I even tweak my day to the virtual environments. Sunrise in a mountain lodge in the mornings, sunny office or ski chalet in the afternoons. Very positively mood altering.
