Latest SDK versions are missing VRC Ultra setting entirely and viewport defaults to mobile, which gets in the way of work due to being unable to see PC-only features such as directional light shadows for things like depth pass (needed for water shader).
Setting manually to VRC High works and play mode will run at what seems to be VRC High, but after leaving play mode, it defaults back to VRC Mobile.
I've tried adding VRC Ultra manually by recteating settings from older project, but restarting Unity will delete said profile.
I've tested on version 3.2.1 and 3.2.3, so I don't know exactly when this issue began, but it's there and it's easy to replicate by making a new world project.
