Hello. I'm trying to get Castles to run smoothly. The problem is that music and sound effects sort of skip every so often and the game performs slowly when certain graphical effects like the cross fade between developer logos and pictures in the intro are taking place. I'm running Windows 7 x64 and I've got an i7 860 processor running at 2.8GHz and 6 gigs of RAM. Cycles are set to max in DOSBox.

Why can't I get smooth performance from a game that ran well on my 33MHz 486 machine back in 1992?

You could try updating dosbox to 0.74, I believe all you need to do is download 0.74 from the dosbox site and replace the dosbox files in the games folder with the new ones.

I'll give it a try. Thanks!
