Btw having played Chaumont on the demo, I have noticed that there is absolute no lag on the orders phase on my 2007 iMac, even though it is relatively big map. The difference to CMBN is enormous, where lag is really tough on the bigger maps - Linnet II in the Great Swan (admittedly a much bigger map again) is almost unplayable for me. I hope this is the same in the full CMFB.
I wonder what the issue is - I know Normandy maps have more details (bocage/trees) which cause performance issues and I also have a fairly full Z folder (but not sound mods) and I wonder if that causes an issue, or whether the fact that CMBN is now a amalgam of several patches, added modules, BPs etc has an effect whereas CMFB is a single product.
Sorry I'm rambling while awaiting the download....
