Sebastiii what could lead to a driver crash with MP but not with MPC-HC? And only with D3D11.
I already installed those drivers. I updated the drivers after I installed Windows 10. The problem still remains...
Edit: (16/08/2015) I fixed the problem! Basicaly, there were many atiumdva.dll files on my PC. Basically what I did was delete the atuimdva.dll file that was modified on the day before the game started crashing. That was the file which was causing the crashes, but I never wanted to delete before because it might cause some problems. But this worked, and now I am able to play Mount and Blade Warband with no problems. Thnx for your attention, BDK.
