Hi,
I'm the person having the issues. I have tried with every memory allocator, and without one, it happens in singleplayer/multiplayer and at the menu, and happens every 10-30minutes without fail
Here are the troubleshooting steps i've taken:
I have tried....=> Upgrading to windows 10, reinstalling the game, upgrading all my drivers, verifying steam cache. Deleting MP mission files, using every memory allocator in the launcher. Full paramaters for my PC. No parameters entered. Deleting dll/physx files, reinstalling Microsoft visual studio C++. Running the game/steam as administrator. Changing my Ram/Changing my graphics card. Using VPNs. I've tried going into Regedit (but the files in WindowsNT I was supposed to change weren't there). I've tried windowed/fullscreen/fullscreen window, all crashing and playing on lower settings. I'm sure there's more I've tried and I've forgotten.
