Often when i play the game, this message pops-up:
"The NVIDIA OpenGL driver lost connection with the display driver due to exceeding the Windows Time-Out limit and is unable to continue."

Never saw this before, but it's the third time today...

"Two possible solutions to try would be:

Reduce the graphics workload if possible, such as rendering to a lower resolution or with less detail.
Increase the timeout to allow more time to complete the really tough rendering parts. Microsoft provides the information on how to modify the Windows Registry to achieve this."
