Just want to also say I have/had this problem. I could never get it to go away, but it can be minimised, playing with settings. But it has been long since I did this, and I cant recall..I think ground detail or somthing...

Just for the record, mods have buggerall to do with this issue. Unmodded games suffer as much from it.

Thanks CirX

Went to the conf.ini file and changed these lines to zero:
LandShading=0
LandDetails=0

The detail factor almost doubled my minimum fps(from 12 to 23 on specific test).
The shading factor added 1 fps more.

Cheers
