The game was running fine with the initial release here on GOG.
I then installed the two patches (offline as I refuse to use galaxy client) and the performance has dropped a lot with dropping of fps for no good apparent reason.
Anyone else the same issue?

EDIT: It wasn't an issue with the game apparently. It was a FRAPS issue, which remains. Of course it is a FRAPS issue when there was no such issue before the patch....so take it as you wish.
