When was the last time you tried it? Assetto Corsa EVO has a Gold rating on ProtonDB[1] and apparently SimHub also works fine, according to the SimHub forums[2].

Yes, I know that they might work just fine on Linux.

But… ACC EVO is alpha at the moment. It barely runs without bugs on Windows. It’s just less hassle on Windows.

The alpha stage is the best time to test if it also works via Wine or Proton -- while you can still give feedback to the devs about it.
