I've been playing through the trilogy recently and have been having this issue in both Marathon 1 and 2 (I'll assume the issue is present in 3). The game keeps taking more and more memory until it eventually crashes. Before it happens, the framerate drops all of a sudden when it's nearing the system's cap (I had a scenario where it took close to 30gbs earlier). The only thing I changed are the graphic settings and I used the same in both games.
