Let me start by saying no other games or software seem to be having this issue on my system. I have gone through many options trying to nail down the issue so that I can play Arma 3 for more than an hour at a time. That being said after roughly an hour of gameplay I will get this error, or a map buffer error and the game will close. I have tried the following: full reinstall of Arma3, switching the drive the game is stored on, verifying game files, deleting player profile, install latest GPU drivers/roll back GPU drivers, updated all drivers on my system, running Steam as admin, lowering graphical settings, both fullscreen and windowed fullscreen modes. Nothing has helped with my issue thus far.
