I was looking for a good WWII flight sim, in retrospect I should have looked into IL2 technical issues closer.
Thanks for your concerns, but I am beyond frustrated with IL2.
Lost all data startin all over to rebuild..steam and cod worked fine. did reinslal today and will not run. Rise of flight fine yesteraday instal. Very upset. I have verfied. removed appcache, restarted. Wish I could just run sim without Steam. They allow me to decribe problem but ask for data I cannot answer so unable to contact suppot. Several comments about steam on google.. all recent months problems.
