Flying close to cloud cover ==> Very low fps and extreme input lag/delay

[RvEYoda]

Had this problem in both lockon and black shark. Every time I fly close to

the clouds under them i get a massive fps drop and very long input delay.

(move head, wait one second, oh there moves the ingame head :P)

 

Is there any way to deal with this?

Currently unable to play with clouds on.
