I don't think I am. Even before Apple released Game Porting Toolkit, Crossover could play the game at nearly the same framerate as native: https://youtu.be/mEZJFjhLAbc?t=46

Looking at this kind of footage really does not convince me that "porting properly done" is worth enduring a library with no games. Nevermind the fact that the game runs fine through translation on the $400 Steam Deck hardware. You really are overstating the difference it makes.

It’s not needed for old games, but as I said: Cyberpunk is an example of port properly done. It’s not something achievable via simulator.
