Game freezing

[madriver86nick80]

Ever since the Steam update my game freezes. No previous problems. Very high end platform.

Same here, more detail:

Game freezes during flight, very low frequency. Freezing on average once every 20 minutes. Sometimes results in a full lock up and game crash (average once every 4 hours). Lock up is preceded by more frequent freezes (once every few seconds). Due to the low frequency of it I'm having trouble isolating it. 

Note: I'm flying in VR, also on a fairly high end rig.
