The same roadblock has existed for ARM PCs as Linux PC - the mountain of legacy stuff that only runs on x86 Windows. Which is something Steam’s Proton has directly addressed.

Now that they’ve wrapped legacy software in an OS compatibility layer (Wine/Proton) and that is being wrapped in an instruction set compatibility layer (FEX) that mountain of software is ready to roll!

Best part is, valve’s contributions are virtually all being pushed upstream, meaning unrelated projects will all benefit from the work.
