Rayman Legends: Definitive Edition is a solid Switch iteration of a fantastic game. However, it arguably isn't 'definitive' - for one thing it lacks a few features from other versions that could have been possible and, oddly, had some minor performance and loading quirks at launch. Our chums at Digital Foundry explained it nicely.
It seems the issues could be linked to the aggressive compression that Ubisoft undertook, which made it less than 3GB and - ironically - smaller than the Wii U version. Based on what we know of the retail model around the Switch, Ubisoft may have done this to cheap out and use 4GB cartridges, as the bigger the capacity of the bespoke media the more it costs publishers; yes, it's becoming a familiar tale.
In any case, this compression seemed to lead to the Switch version having longer load times than any other version, and even brief framerate issues as the game unpacked assets. Ubisoft has finally address this, issuing an update and the following patch notes.
We appreciate your patience concerning performance issues that some of you may have encountered while playing Rayman Legends: Definitive Edition on the Nintendo Switch. This latest patch, available for download now, reduces loading times between levels and fixes frame rate-related issues as well.
It's good to see those improvements coming into place, and it'll be interesting to see whether the patch fully resolves the minor but noticeable issues with the launch build.
