I found the HD stuttering ok actually, but I've not moved out of the first town.
I'll give the new version a try tonight, and have a play with the midi bits and bobs.
I've found that pushing smooth scrolling to 50% helps, and setting the map draw size to 320x200 also helps a bit. Having said that, 320x256 with map size at auto didn't slow things too much. I'm interested that rodpulsar managed a higher resolution, I'll give that a try too.
Mad-Matt, are you saying that it should be possible to get midi music runnig on a normal Amiga? Can you give some specific instructions on how to achieve this, or is it a matter of moving the camd library into LIBS and then installing gmplay/softsynth? Are these easy to setup?
