Don't you mean 68k Mac? If so then it does scroll smoothly. Shapeshifter the emulator pretty much craps out when trying to emulate Worms and Lemmings and quite a lot of other high resolution games.
Also you can't compare the Shapeshifter emulator to real 68k Mac performance.
For example it won't run Dark Forces, Shapeshifter is decent for desktop stuff just not games.
