No, I'm playing the Steam unmodded game. Sometimes it works like it should but most of the time it's really slow (even the aerial battles are slow). Only the ground combat works as usual. I think it may have something to do with my PC (I'm playing at work with a very old PC, it's above the minimum requirement but still quite old).
