Anyone trying to play Carpiquet in real time is braver than I am. There's also a lot of 'content' on that Northern Master map such as different textures, flavour objects etc so the game needs to load quite a lot up front. Try scaling down textures and model quality prior to loading if you hit troubles.@Concord, I know with @Ithikial's WWII Lions of Carpiquet some players have had crashes on some of the larger maps, this is during gameplay with heavy artillery and on occasion trying to play real-time. I've had no issues so I'm guessing it's rig related. You could take a duplicate of the map then cut each in half so map A is north, map B is south, and work on them separately. You're going to cut up the map for gameplay anyway.
In a CMFB PBEM I'm playing (A war without mercy), there's two rather large towns in a big map. Plus there's a brigade of forces under my command (US), while I guess a 1+-2 battalion worth of infantry and ~2 companies (?) of German vehicles. While we're straining the engine, it has hold up so far and we're nearing the end. The mental effort to play the thing is also quite heavy, but rewarding at the same time.I noticed on the Battlefront website they advertise the games as 'up to battalion' size, so maybe we are pushing their engine far beyond expected loads.
