There are translation layers to run x86/64 code on ARM, I don’t know how easy it will be to do the same work on RISCV, but I’m guessing if the will is there, the code will follow. But I’ve yet to see a RISC-V chip that gets close to the performance if a modern ARM or x86 laptop/desktop class device, so that translation might be useful to help close gaps, but I doubt anyone is going to be doing real gaming on RISC-V this year.
