I have a subset of my users who always see all meshes at the lowest-possible level of detail meant for distant objects, even when up close. Some of these users have high-end devices, all have stable internet connections, & all of these users have this issue permanently, with no rejoin ever fixing it (& nobody without this issue has ever experienced it, it’s all or nothing). Affects PC & mobile devices, unsure of console.
Have not run into this issue myself but it’s such a crazy low-detail version that it’s impossible to tell what many objects are, & it’s important for gameplay to be able to see things, in general.
Example from one user:
MeshStreamingAndImprovedLods enabled:
(grass + the soccer field lines + etc. are ultra-low-detail)
MeshStreamingAndImprovedLods disabled:
(grass + the soccer field lines + etc. now appear as authored)
Same user had no issues after MeshStreamingAndImprovedLods was changed from Enabled to Disabled
