Some photogrammetry data is that poor. However this also looks like it’s not fully resolved yet.
Where was that screenshot taken?
And does it get better if you ‘hang out’ in the area, paused.
You internet may be fast but there are many other factors at play. What is your terrain detail (LOD) set at for example? If it’s very high the sim might be busy updating tiles far away.
To make sure everything is loaded, check the performance monitor and leave the game paused until it stops receiving (significant amounts of) data.
I have shots of the Orlando area from my world tour leg through there
PG data is not meant for ground level viewing, I’m about as low as it allows to still get good quality visuals. Not all PG areas have the same resolution either, perhaps you were in a low detail area.
