On April 16, Nintendo released the 8.0.0 update for the Nintendo Switch, which added several new features to the system. The 8.0.0 update allowed the player to reorder the games in their library based on different criteria (such as length of time played), it was made easier for players to transfer save data between Nintendo Switch systems, and it became possible to zoom in on different parts of the screen by double-tapping the Home button.
It seems that Nintendo hid an important feature in the 8.0.0 update and neglected to mention it in any official documentation regarding the patch. According to Digital Trends, a feature referred to as "boost mode" allows the Nintendo Switch to temporarily overclock the CPU to 1.75GHz, before dropping back to down to the regular 1GHz.
The most recent updates for Super Mario Odyssey and The Legend of Zelda: Breath of the Wild added support for the Labo VR set, but it seems that their updates also allowed them to benefit from the boosting feature of the Switch. There have been reports of the load times in The Legend of Zelda: Breath of the Wild being slashed by a third and how it's going to affect speedruns of the game going forward, while Super Mario Odyssey has also seen a marked improvement in its load times.
It's possible that the improvements to Super Mario Odyssey and The Legend of Zelda: Breath of the Wild are a test run for Nintendo to determine how feasible the boost mode is and whether it can be applied to other games that have already been released, which would require further updates. There is also the question of whether the boost mode will become a standard feature for Switch games going forward.
The Nintendo Switch is the least impressive console on the market in terms of its hardware, but Nintendo has done an incredible job of making its first-party titles look amazing in both docked and handheld mode. The majority of the first-party Nintendo titles also manage to have a small file size, especially in comparison to a lot of third-party developers and their 40GB games. The Switch has never had a reputation for having slow load times, but the increased speed offered in the 8.0.0 update is a welcome addition to the system.
