yeah vsync to 60hz works Perfectly smoothly on games,
exactly like a real amiga. but vsync on,
enables more precise
chipset timing in the emulation, and hence the emulation
suffers. like in workbench for example boot times and load times are greatly decreased i found. as with boot times and load time with games. it's pretty much as fast as a real 040 amiga 1200. loading from a standard IDE drive.
so the solution is only turn on vsync to 60hz for games.
