Invisible Chopper

[sgrig]

I don't know if anyone has encountered this. Basically quite often when a Gunship is in open terrain, only the rotors are visible, and the rest of body disappears!

I have the following specs:
Pentium M 1.7GHz
512MB RAM
Nvidia Fx Go 5200 with 64MB RAM
Win XP SP2

I attach a screenshot of this where a chopper in open terrain is invisible, while the one in a city is fine.

I have a nvidia Geforce 6800 OC and 512mb of RAM and have the same problem. I'm seeing lots of problems with people with who have 512MB of RAM.
