Fixing The Cyberpunk 2077 AMD Ryzen CPU Core Issue

Technology · December 14, 2020

I have been absolutely enjoying Cyberpunk 2077, despite only finding the time to clock a few hours in the game. As an owner of an AMD Ryzen 3900x, like many Ryzen owners, there are known issues with core utilisation on Ryzen CPU’s.

I’ll be honest, on my 3900x I had not noticed really many issues. I have experienced frame rate dips in the game but assumed it was optimisation related to the game itself and not core utilisation. So, naturally, I was curious about this fix that someone on Reddit discovered.

If you are using a lower CPU like the 3600, admittedly, you are probably going to notice if your CPU is not being utilised properly more-so than you would on the 3900x for comparison sakes.

The solution involves editing your cyberpunk executable file in a hex editor and changing some values. If you’re not technical, this might be a bit much for you, but the process is quite straightforward if you’re brave enough to do it. If you backup your .exe file first, there is no harm if you mess things up.

  1. Download a hex editor, like the free one HxD from here.
  2. Open up the cyberpunk executable file (depending on where you installed the game) and make sure it’s not the launcher for the game.
  3. Look for 75 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08
  4. Change it to EB 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08
  5. Save the changes and open up the game

As for the “why,” this fixes the issue or what this even does, admittedly, I have no idea. All I know is after making this change, even though the game was playable for me on my 3900x and RTX 3070, the game was noticeably more performant.
