Gameplay is choppy at times, but I have enough CPU power? Although the FPS counter shows 100% speed for these games, they may appear choppy. This is true to the original — even the original hardware of these games struggled with them and therefore the choppiness is actually accurate emulation of these games. You may be able to get rid of it in some cases by using the -cheat parameter, hitting the tilde key and browsing the on screen menu until you find 'CPU overclocking'. This will run the emulated CPU faster which may or may not fix it. It may also cause the emulation to have errors, so don't bug people if overclocking screws up a game.
