lag in editor, and slow f10 map when flying

Hello

I am having allot of lag with the new Persian map especially in the editor.

Example 30 minutes ago i started up the editor and wanted to create a mission.

The first 5 minutes when i see the map in the editor I had to wait for the map to finish loading, and everytime i zoom out it took a long time for it to update and expand the map.

I could also not slew the mouse arround for a few minutes.

I also have a slow map/lag when I am flying a mission and press F10 to bring up the map, then the map lag, and is a bit slow to expand..

Non of the two above way feel smooth to me.

On other maps I do not have the same issues, its only the persian gulf map.

I dont know if i can delete some kind of cache or config file to fix the problem, or if this is a bug.

Also after about 20-30 minutees of Online playing with 4 other people, then typical in VR the persian map FPS are reduced to about 2 pr seconds where i can just sit and do nothing.. it take about 10 minutees before the FPS return so i can play. This do not happen on caucasus map.

PS.. i know my computer is overclocked... However i also tried with std speed and 2400mhz ram and i have the same issue with the map.

ryzen 1800x 3900mhz ( overclocked ) 8 cores / 16 treats

( temp below 60degrees )

16gb ram 3200mhz ddr 4 ram

Nvidia GtX 1080

windows 10 64bit

DCS is installed on 2xSSD running in raid 0

Antivirus have been configured not to scan the dcs folder.

The above happen both in VR and without VR.

PIMAX 4k VR headset. ( it uses htc vive software to run ).

just to be clear, this isn't just the first load is it (while effects etc. are compiled for the first time)?

It also happens when you return to the map after a mission ?
