RC version 1.54.133479 crashed my graphics driver and the game had to be terminated. I had played around half an hour in singleplayer scenarios and suddenly without any warning or specific actions the driver crashed while flying a helicopter. This did not happen in the recent past versions. This was the first occurrence in a series of successful runs.

The PC manufacturer has classified the driver in use as very stable and I am unable to update it due to OEM restrictions.
