When the Nintendo Switch 2 was first unveiled, there were plenty of parts of its specs sheet that drew attention, but the inclusion of a 120Hz display was surely one of the most eye-catching inclusions. This means that games on the Switch 2 with some headroom in terms of performance can enjoy ultra-smooth performance, whether in handheld mode or when connected to a compatible display.
The reality, though, is that the there haven't been all that many games in the year since the Switch 2 arrived that have taken advantage of the feature. While the Switch 2 is drastically more powerful than its predecessor, it's also far from the power of a PS5 Pro, for instance, so only less graphically demanding games have a shot at utilising 120Hz mode properly.
