Whatever graphic configuration I use, I have large fps droop inside cockpit. When I use F2,F3,F4 or even F6 views I have average FPS around 80-100 FPS but inside cockpit FPS drops to 20-30 FPS. Is it normal or I need to change something? 
My PC config  
CPU- Q9550 @ 3.4 
MEM-OCZ XTC Platinum 4*1024 MB @ 400 
GPU- BFG GTX 295 @ factory settings sometime I use (650/1400/1200) 
MB- Gigabyte GA P35 DS3 rev1.0 
Graphic res 1680*1050 
Win 7 -64bit 
Also several times game freeze and I see that my GPU-s have 0% load (sometimes it is going to last 1-10 sec and game continue to work and sometimes just freeze). Have latest drivers from Nvidia - 266.58 
This problems are happening in 32 bit or 64 bit game. 
Looking forward for some tips or suggestions about this –let me say- problems.
