Varies by game. Primarily three types
- Games with free upgrade patches (Pokemon Scarlet and Violet, Legend of Zelda: Link's Awakening etc) - these run considerably better with higher frame rates and resolutions. The difference is typically very meaningful
- Games with paid upgrade patches (Mario Party Jamboree, Legend of Zelda: Tears of the Kingdom etc) - these also run considerably better with higher frame rates and resolutions, however to access the enhanced performance you'll need to buy an upgrade pack. These paid ones typically also include Switch 2 exclusive content (eg new modes in Jamboree)
- Games with no patches. These may or may not perform better. They'll run at the same resolution, but if they struggled to reach their frame rate cap before, they may be able to brute force it now. Loading should be better also. How much this has an impact varies by game, but either way don't expect miracles.
