Remember when the Allied Assault Demo was released, everyone had problems with Frame Rate... Im sure they'll clear that up once the game is released. Also, most demos run slower than the actual game does... And I've also noticed that the sub pen level is slower than the Malta level. Malta runs fine on my machine, but i get some slowdown on the Sub Pen. just like in Allied Assault, some levels run faster than others. Take "The Bridge" for example. It runs a lot slower than "Algiers". The sub pen level might just be one of thoes slow running levels. Anyway, im sure when they release the full version, the Frame Rate will speed up.
