I’m not sure if this is the same issue as before with scaling but in VR the panel is noticeably more fuzzy and undefined after the update. Is this something you can fix (again)?
It seems to be an anti-aliasing issue introduced in VR mode in SU5, and as such we are unable to fix unfortunately, only Asobo can. It’s been mentioned in a few reports over at the MSFS forums too, e.g. Cockpit Graphics Quality after SU5 - #2 by CalmEspresso - General - Microsoft Flight Simulator Forums
Please report it to MS in their channels.
