I have still lot of trouble when running IL-2 1946 4.08m or 4.09mB1 with Vista OS. After a randomly changing period of Time (10 mins up to 2 hours) the game freezes and the following message is displayed:
'Display Driver nvlddmkm stopped responding and has recovered'
I googled for nvlddmkm and got more than 40.000 hits !!!!!
Okay, if you have the same problem with nvidia drivers you can read this
NVIDIA Statement on Timeout Detection and Recovery (TDR) Errors
to get more information.
But most important: Launch a bug report at the Nvidia Quality Assurance site using this form
Nvidia Windows Vista Graphics Driver Bug Report
Only if many users launch a bug report Nvidia will react and release a solution for IL-2 with future drivers. We should use the power of our community to get a solution.
Many thanks for your support
