This is the general error that i get. Along with many others it is an issue with the Physx3_86.dll. Most of my crashes happen right after an explosion of a vehicle or large shell within close proximity. I know many servers whos admins have stated this is the cause of the crashes.
I am running 12gb DDR3 GSkill ram
AMD FX8350
Radeon HD 7850
MSI 890FXA-GD70 Mobo.
