1. A Linux VM which has steam installed on it.
2. A project like virglrenderer[1] for macOS and which processes Vulkan commands from the VM with virtio-gpu and sends data back. (I don't exactly know how it's done.)
This would allow games on the Linux VM's steam run at near-native GPU performance.
On the CPU side, there still a need for instruction emulation like QEMU. Or, Apple posted somewhere that you can run x86_64 Linux binaries inside the VM with the help of Rosetta. or an ARM64 Linux VM with Steam running via FEX-Emu.
