I just experienced an extremely bizarre freeze where the client appeared to CTD, but I still had the Arma 3 cursor and I couldn't click on anything. After killing the game with task manager I figured I'd check the RPT but I noticed there was also a crash dump, so here's the dump in case it helps:
Unlike usual I didn't have any mods running. I was just messing around in the editor setting up a bug-reproduction/benchmarking scenario when the freeze occurred.
So the same thing happened 3 more times, and I checked the Windows event viewer and apparently it was a display driver crash each time. This makes no sense as I'm able to run MSI Kombustor without incident, but I guess it's not the game causing it so I suppose disregard this report.
Edit:
Also, for some reason Visual Studio insists that the cause of every crash I try to debug is
The thread tried to read from or write to a virtual address for which it does not have the appropriate access.
Doesn't sound very much like a display driver issue to me. I guess I should stop believing Visual Studio every time I report a bug on here.
