Ah yeah I think there's a collection of issues related to small text within XR! The biggest one is really pixel density on XR headsets, which is always an issue for small text, or far-away text. XR also can't benefit from sub-pixel approaches to font rendering either. Since you can always move further from text, there's also the IRL issue that the text is just too far to make out!

The current raster technique should actually be fine for smaller text, there's some super-sampling going on in the shader that should help a bit here too! I'm not entirely certain what else could be improved on in this case besides font selection, I'd be open to suggestions or tips :)
