> Since Dolphin is a JIT, this seems to be a case of where Rosetta's JIT is smarter than Dolphin's in terms of which ARM instructions are chosen when converting from the Intel instructions than Dolphin According to the article, the AArch64 JIT isn’t as complete as the x86 one so some less common instructions are emulated, not JITed. I imagine a game that uses a lot of these is slower with the native ARM version.
