'Trailers for TotK have showcased new physics interactions that may pose a challenge for emulation, as similar mechanics were difficult to emulate in the early days of Yuzu with BotW,' he says. Nintendo's optimization and engine changes are the big unknowns here. Bunnei was able to elaborate on what kind of obstacles they'll likely face when Tears of the Kingdom hits.Ģ017's Breath of the Wild wasn't particularly optimized for the Switch's Nvidia GPU, which makes sense-it spent most of its life in development for the Wii U.

Console developers, meanwhile, notoriously find clever ways to squeeze the most performance out of their hardware, and figuring out those tricks is a big part of improving emulator compatibility. Emulation poses greater bugfixing challenges, because these volunteer developers are trying to replicate how an entire system performs.

I'll admit a tiny part of me was hoping for a wildly confident '100%', but a nuanced we'll see is the practical answer-heck, it's a toss-up whether native PC games are even going to work properly on day one.

Above: The Steam Deck can't run Breath of the Wild on Switch at 30 fps.
