This only applies if you don't have an Intel CPU. The instructions can be found on reddit (link below). The only thing I want to add is that you need to backup your .exe before you screw around with hex-editing it. I'm skipping Cyberpunk 2077 for now so I haven't tried this myself. It just seemed too genre-appropriate to not post.

EDIT: Corporate kill-team got the post. Here's a different way (and easier) to do the same thing. https://github.com/yamashi/AmdCyberpunkPatch/releases/tag/v0.1.2 . Don't forget to back-up the stuff it replaces. Also try the game first and then hack it afterwards to see if there are improvements. Hack the planet!
Not really specific. Just LLVM on Playstation and MSVC on X Box. These give output which is not crippled though. It is also typical to tune compiler options carefully.
You could not edit the console game though because the files are signed and would be invalid.
