    Translation layers aren’t porting

      Fair enough, but to the end user it doesn’t matter if it works.

        Emulation is always slower and eats more battery. Microsoft’s laziness is proof they don’t care about that hardware, so may just as well buy an iPad Pro instead.

          To add to what the other person said, there are some Windows-only games even today that run better on Linux than on Windows (I don’t have examples off the top of my head.)

            Yuzu can exhibit superior performance because the Switch is rocking the Tegra X1 from 2015. Yuzu absolutely cannot beat the Switch with contemporary hardware and/or comparable power consumption.

              But yuzu was running on the switch in that example. So it was beating the switch on contemporary hardware.

                Oh yeah, clearly I did not read the article well. Still, it doesn’t mean what you think it does.

                First, Yuzu is more of an alternative API implementation than an emulator in this setup. The stock Switch OS and API implementation have been entirely replaced with Linux and the Yuzu implementation of the API. Given recent performance uplifts in the Linux kernel, I’m not surprised that Linux+Yuzu beats the first-party implementation.

                Second, the use of the word “emulation” in the above thread is really a misnomer: Rosetta 2, Prism and the like all perform what is called dynamic ISA translation. Yuzu need not perform ISA translation when running on ARM hardware.

                  I’m also not surprised and I still find it amusing. The ISA translation is something I never actually thought about in emulation

                    It is always quite amusing to see a billion dollar corporation beaten in its own game :)

                    More information/context, if you’re curious:

                    Rosetta 2 in particular isn’t full emulation because the API is the same for both architectures - it is only dynamic ISA translation. I expect that Prism will be slightly closer to full emulation; there is simply no way Microsoft will reimplement all of the legacy Windows APIs on ARM.

                    WINE is a great example of something that is also not a full emulator, but for the opposite reason: it does not perform any ISA translation or hardware emulation, but rather only syscall (API) translation.

          Its not laziness, they have lost developers support over time and lets be honest here, Windows 8 arm was roundly laughed out the door. Expectations are now marketing hallucinated by copilot.

          This is typical Microsoft “agile”: minimum effort and delivery.

          Emulation is almost always slower and eats more battery.

          FTFY. There have been some cases where emulation actually outperforms native execution, though these might be, “the exceptions that prove the rule.” For example, in the early days of World of Warcraft, it actually ran better on WINE on Linux than natively on Windows.

            WINE literally stands for “WINE Is Not an Emulator”.

                To be fair this is also a translation layer and not an emulator.

                Prism is an x86 emulator for ARM. If you think that Prism is “a translation layer and not an emulator”, I refer you to the very first word of the second to last paragraph of the submitted article.

                  That’s assuming the writer knows what they’re talking about. Last line from the second paragraph:

                  Windows 11 has similar translation capabilities, and with the Windows 11 24H2 update, that app translation technology is getting a name: Prism.

                  And first line from the third paragraph.

                  Microsoft says that Prism isn’t just a new name for the same old translation technology.

                    Certainly more than you because Prism emulates an x86 CPU and WINE doesn’t, therefore the WINE comparison is still wrong.

                    Edit: Please prove the writer wrong.
