RISC-V CPU runs The Witcher 3 at 15 FPS — 64-core chip paired with Radeon RX 5500 XT GPU deliver laggy gameplay

At very low, choppy FPS for now— but that it can run at all without x86 bodes quite well for the future of RISC-V devices

    Were they emulating the x86 code in realtime, or pre-translating it to RISC-V in the way that Apple’s Rosetta 2 does for ARM? If the former, that is indeed impressive performance.

      I don’t even care. The fact that we’re at a point where it runs means a whole bunch of "step one"s have been succefully taken.

      Besides Box64, which was used to emulate x86 instructions in general, Wine and DXVK helped fill the gaps using Linux instead of Windows.

      Believe it or not, the article answers that question. The linked blog post from the devs has even more detail.

      The original blog post (linked in the article) refers to this as a DynaRec, i.e. a dynamic recompiler. So it’s not exactly emulating, but nor is it the ahead-of-time recompilation that Rosetta 2 can do.
