However, most AAA games are made with consoles in mind, so if i do want to play one, i'll get it for my PS4. It happens pretty rarely lately, though. Huge backlog of Mac indies to play, sorry AAA companies.
About the Witcher 2, the performance on Mac (and I guess on Linux too) was crap on launch. And that's what most people who bought the game saw, because they didn't expect the ports and bought when the Windows version launched and dual booted. Whatever they improved, it was too late, everyone had finished the game by now.
As for Witcher 3, I bought it but I only got like 1/3 of the way through it. Why? Because it only runs on Windows (I haven't tried Wine lately, so this may have changed) and rebooting to play a game is disruptive to all the stuff I run on the Mac OS side of things.
That doesn't bode well for my chances of rushing in and preordering Cyberpunk, sorry CD PROJEKT.
Edit: please no one explain to me how Macs don't have the hardware to run games, I hackintosh, have a proper video card and stuff like the ports of the Metro games work just fine(tm).
