Overclocking

Once upon a time, there was the Sega Gensis. The Gensis was a video game system of great popularity. However, a lot of the older games, the ones that were closer to the end of the system's lifespan, were extremely demanding on the hardware. So when the system got overworked, it woudl start slowing down. The complicated games woudl work the CPU too much and you woudl see certain artifacts. Well, less artifacts, more slow-down, to make it clear.
