Factorio and Minecraft (Java edition) are two of the few games that come to mind where the Linux port got comparable effort to the Windows port, and I don't think people are in a rush to play either of them in Proton.
Your latest AAA open world RPG on the other hand? Yeah, you're probably going to have better luck in Proton even if it gets a native Linux port.
