I have implemented the modifications recommended in this thread
For me it has improved my experience. Ive gone to LOD 5. This has not reverted the sim back to how it was, but it has ‘improved’ it some.
Ive still not been able to exit the sim without it crashing, there is still a ton of pop in, there is still areas of barren landscape in urban environments. All reasons why I havent done another full flight since I put the above post up.
Will have another go today and see how it pans out.
