Same here. This thing runs as smooth as no other CM before for me (and I play CM since the very first CM). As I first fired it up today I thought thats this is so good looking right out of the box that I dont need any mods.
For me its the best CM so far. Good job BF. Keep it up.
I have it and I dont like it very much. Its realtime and Iam not a great fan of realtime. The UI is awkward and I find the behaviour of the Infantry extremely stupid. There no decent manual so it takes some time to get used to the game system and for me this is the biggest drawback. Its not my cup of tea but many peopel like it. But I think for 7$ its worth a try maybe you like it.
I just installed it and everythings fine. Have you installed in the right directory? Its under "MY Computer/Documents/Battlefront/Combat Mission/Fortress Italy/Game Files/Scenarios.
