Have you tried turning off cache chipRAM? It works for me.
With the latest version everything is fine, but thanks for the response (perhaps this is already off in my config, i have to check that).
@petarku : i manage to save some time to have a small minimig session and play canon fodder First this game is great, too bad i could not play longer, second, i did not notice any scrolling pb appart the inherent slow framerate during the game itself. By the way, just before the mission, there is a cinematic with an helicopter where the scrolling is perfectlty smooth (my guess is 50Hz), do you have also pb there?
