I wouldn’t say that’s a universal truth. Some games perform like shit on Yuzu and others that simply aren’t stable. Yuzu is pretty damn good, but I’ve run into plenty of situations where graphics have lots of glitches, I’m crashing every 20-30 minutes due to a memory leak, etc. E.g. SMTV is one I recently opted to just play on my Switch natively because I got tired of random freezes after battles.
