Got this physx crash lately in multiplayer games (a 50 people server). Before I could play for hours without a problem, now the game crashes every now and then. The last times I noticed that I was doing nothing special, but just running through the world.

I have an AMD graphics card and so I thought physx is not used. After about the half of the crashes I installed Nvidias Physx driver, but that does not changed anything.

I attached all of the dump files, dxdiag and the windows event log: Arma3_physx_crashes.7z (10 crash reports, 7 dumps)
If you need anything let me now.

Graphics: AMD Radeon HD 6970
OS: Windows 7 64 Bit
