If I play a new campaign as Union, towards the end of the first battle (when the third reinforcements arrive), the game crashes with the error: " The NVIDIA OpenGL driver lost connection with the display driver due to exceeding the Windows Time-Out limit and is unable to continue. The application must close."
This error is listed at http://nvidia.custhelp.com/app/answers/detail/a_id/3007/~/opengl-message-%E2%80%9Clost-connection%E2%80%9D
I'm running a laptop with NVIDIA GT 555M 2GB on an Intel I7 with 8GB RAM. I tried lowering the resolution with no effect. I still have shadows and transparency on.
The crash seems to happen always at the same time (right after the third wave of union reinforcements arrive).
