In SP i can turn up most of my Settings and fly a comparable Sortie without no Problems at all. MP however would be next to impossible to fly at those settings, independent on side chosen. I suspect the problem lies in the way the server is setup. Remember, it is not a dedicated server, but more comparable to a listen server. Who knows ( Serveradmins step forward pls and enlighten me
) what unnecessary files the server has to load, which in return has an impact on performance.
