mario galaxy full speed question

[JMC47]

The games are still running full speed, they're just rendering at a lower framerate. They can do this because they're designed to run on multiple PCs, which means they're not guaranteed to run a certain framerate. They're skipping frames, rather than running slower usually. Even when running slower, they'll still be running full speed. If you have a virtual machine running a game and the virtual machine was lagging (Let's say you have a Core i5 3570K emulating a Core i5 4670K or something, and that was possible to do with cycle accurate timings) you'd get audio stuttering or something. Theoretically.
