FREEZES in PG LOW LEVEL only

i mentioned this 2 weeks ago, i do get freezes and stutters when descending towards ground targets in PG, if i manage to climb again those freezes disapear.

log is attached,

memory usage was about 23GB!!!!!! the rest of the 32GB were on standby too, so 100% used

WIN10,i7 4771,32GBRAM, SSD

when i last time reported this issue it was forwarded to RAZBAM, because of flying the AV8B,

I highly doubt that this has anything to do with the AV8 only, so please can a DEV have a look at?

mission length was 74mins

unfortunately the track file exceeds the forum MB limit so check the dropbox link

grass was at 0

trees at 0

maybe this has something to do with textures of the streets/ground/lamp posts ????
