With the move to 3D, however, it took much more CPU power to run games at 60FPS. So few Most early 3D games actually ran run at that30FPS. Most ran at 30FPS, and some Some run at 20FPS, or even lowerframe rates. The Legend of Zelda : Ocarina of Time , for instance , runs at 20FPS. Star Fox ran runs below that.

If you are experiencing slowdown, it may be that the emulation is too intense for your system. When this happens, both the video and the sound experience slowdown. To counter act this, you can enable speed hacks, use a less intensive emulator/settings or get a new CPU. However, the slowdown may be part of the original game, and will be emulated. As such there is nothing that can be really done, short of reprogramming the game itself or emulating an overclock. When this slowdown occurs, the video will slowdown but the audio will often continue at full speed. An example of a game with real slowdown like this is Metal Gear Solid (PS1).

==SpeedhacksSpeed Hacks==Using speedhacks speed hacks can affect '''both''' types of FPS in emulators. Most of the time it only affects the emulator's these are used to alter emulation, sacrificing accuracy for speed though, to help achieve 60/60FPS. Some speedhacksspeed hacks, however, can lower the internal FPS to raise the emulator's FPS; an example of this is in [[PCSX2]], known as EE cycle stealing, which reduces the clock speed of the virtual CPU used, the Emotion Engine. No speedhacks raise the  There are a few game hacks that optimize game code in order to remove possible instances of in-game slowdown. There also exist a few speed hacks that increase a game's internal FPS, as this should always be at maximum unless altered as previously mentionedframe rate. They only function properly in emulators with overclocked hardware.
