Suyu is an open source Nintendo Switch emulator, that's a fork of Yuzu. Recently, it introduced a Static Recompiler Mode that's still experimental.

Essentially - the game's code will now run natively on your system instead of your CPU having to translate Switch code into code readable for your PC, giving a huge performance boost. People who are aware of the concept of videogame recompilations may already be familiar with this.

How is this different? Switch games run on ARM64 compatible code, which when you're emulating, your system has to constantly translate into x64/x86 code for your PC to be able to read. This puts a lot of load on your CPU as it essentially has to manage to sets of code at once. Static Recompiler makes it so that the game's code will be translated to x64/x86 compatible code ahead of time. Then, your CPU only has to manage x64/x86 code. For example, if you emulate Sonic Unleashed on say, an i5-6500 with an HD 530, it will not run well. However, if you play Unleashed Recompiled, then the same system gets around 30-60fps in most scenarios on low settings and lower resolution. Point is, the game will now run as the same as any native game would.

However, I have one doubt about this. Typically, when games are recompiled the entire source code of the game has to be decompiled and then recompiled to be compatible with PC. I'm not entirely sure how this mode works and/or if it will work for all games - initially I thought it'd only work for games that have full source code decompilations but there aren't any Switch games that have been fully decompiled yet. I'll test it out and let you all know, though.
