"Why is it so slow in the puzzles?
This game makes extremely heavy use of the framebuffer during these sequences, making multiple rapid texture downloads for the animated puzzle effect. This can cripple even a high spec. PC. It is suggested you temporarily turn off the emulation of this effect while you complete the puzzle to improve performance. To do this, uncheck Self-rendered textures (video plugin, ROM Settings tab). When you have completed the puzzle, you may wish to turn this back on so as not to lose other effects that the game is using this feature for, such as the menu background."
