Uncapped framerate option and freesync nextgen?

[SvennoJ]

Hdmi 2.1 will support freesync or something similar. I doubt all tvs will support it though, it will be an even lower adoption rate than 4K.

It depends on how simple it is to switch to uncapped frame rates without any side effects. For example with fsx I had to limit the frame rate so the terrain generation could keep up. Letting the gpu run as fast as possible leaves less time for gpu compute actions for streaming and procedural generation. Plus you probably want to avoid games that swing wildly from 30 to 50fps.
