>they’re using to help developers port their games like what Valve is doing with proton. Well Apple and Valve are doing exact opposite things with their tools. Let me explain. Valve runs your windows game unmodified. There is no 'porting process' and there is no 'port'. As person working with large publisher I am still in shock and disbelief that it is legal and works well in practice but here we are. The funny part is when developer of windows version of a game is asked 'how well do you support Steam Deck?'. And developer has to do windows version changes and produce new windows version that has tweaks for Steam Deck.
