Some original Switch games will run better on Switch 2; some won’t run at all

Summary

We've known for a few months now that the Nintendo Switch 2 will support backward compatibility for older Nintendo Switch games, and as of today's presentation, we also know that some Switch games will get special Switch 2 Editions that add new features and support higher resolutions and other features.

Compatibility testing is ongoing We still don't know whether non-updated Switch games running on the Switch 2 will perform better by virtue of the updated hardware; we'll have to wait to test the console ourselves to know for sure.
