There is now a more energy-efficient way to fastforward. Instead of relying on the CPU to be as fast as it can be to fastforward frames (the default and only way up until now), now it’s also possible to fastforward based on ‘frame skipping’. To be more precise, this method of frame skipping is done by measuring the frame time and skipping based on frame time.
Some advantages to this new way of fastforwarding:
- GPU MHz stay down, which is more energy efficient than presenting frames that are not visible anyway
- Fast-forwarding with 3rd party frame limiting such as scanline sync is possible
It also means that with this option, fastforwarding is now possible for more cores on lower-end hardware. For instance, in the past, if you wanted to fastforward by x 2 in a specific game, the CPU of your machine had to actually be able to run the game with the core twice as fsat as the normal default.
