Do you think it could be related to the boarding passengers?
That would be easy to try: just dock/undock a jetway, without calling boarding/deboarding.
I based this change on a recent report that it was enough to operate jetways to trigger the blurries and, in fact, found a place where I could optimize this. But, apparently, that's not the issue. I'll await further reports though.
OK - so I did this test: I parked at a remote stand at EKCH (FlyTampa), GSX jetways active, new bglmanx64.dll, 1K jetway textures. During boarding, there is some stuttering. If I jump to an AI aircraft while the passengers are boarding, the textures take a while to reload (that's understandable really). The main point is that the textures - both autogen and ground - DO reload eventually. And I get crisp ground textures, no blurries.
Can someone else test this? Remote stand, board passengers using bus with GSX L2.

EDIT: I tried this again - all textures load perfectly. No blurries. So - for me - it is most definitely a question of actually USING the jetways. They can be active, but mustn't be actually extended. Perhaps it has something to do with boarding the passengers through the jetways. I will try just moving the jetways but not boarding passengers. Maybe something else can also try this.
EDIT#2: I was wrong.. about 15 minutes into the flight, the textures stop loading and it gets blurry. ORBX textures (Germany North) don't load at all (pic attached). Damn it !!! And this is without using the jetways! OMG...
