It is also my conclusion as this morning again after I did all the cache “cleaning”, I landed in Singapore with no scenery once more.
I am planning to use FSLTL too and see if the problem is somewhat reduced. The other solution I thought about was to use the MSFS Live Traffic, but that would be a last resort.
It is rather bizarre that so few complain about this issue as it is a major drawback when one flies airliners, most of which would land at major airports where traffic will be an issue.
In my latest case VTBS is a major airport, but VTSP is not, nevertheless, the number of objects was still exceeded before I left, hence no scenery at destination! This is exceedingly frustrating.
