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!
