ISSUE DESCRIPTION

Description of the issue:

I know this is a previously documented bug but on my system I had seen this frametime spike (fps drop) reduce to almost being insignificant in recent beta builds. However in 1.8.10.0 this spike has become worse than ever and not just on the initial touchdown but I then experience it multiple times when taxiing. It’s so severe that it feels more of a jolt than a stutter. I’m testing on exactly the same settings/aircraft/airport as previous betas so this is not due to a change in testing. The problem is seen even a very small airports.
