Sorry, but I had never any problems to run any of the IL2 original to the IL2 1946 with the same pc and I have never know anyone in my friend that had any problem with it. Lock on yes IL2 no! Only with COD did some stutter appear with a new and more formidable pc. But this is the consequence to a new a way of codding of the environment by the development team. Beautiful but heavy and complicated.
