About This Mod

The solution is a bit questionable (although it is currently 100%!!! tested), but since I couldn't find any points in memory to prevent these calls, I just found each one and fixed them with nop (No OPerand, meaning "do nothing").

The cut-out instructions will have no effect on the code, since I save all register values, which would be the case if it were executed on an AVX-enabled processor. These are just instructions for checking some data, and after the patch the code has not changed compared to the stack trace on the AVX-enabled processor.


I previously tried to download a fixed Cyberpunk2077.exe, but it was marked with a false positive, so instead I made a script that fixes Cyberpunk2077.exe on your computer.

Just download the zip file and follow the instructions.


This is a patch script that will remove all known AVX statements from Cyberpunk 2077 v1.3.

Extract the files to the game installation location where Cyberpunk2077.exe is located.

For example, c:\Program Files (x86)\Steam\SteamApps\common\Cyberpunk 2077\bin\x64\ (Steam, but the patch works for the GoG version, only the path is different).

After unpacking, run Windows Powershell as an administrator and navigate to the folder where Cyberpunk2077.exe is installed.

(cd c:\Program Files (x86)\Steam\SteamApps\common\Cyberpunk 2077\bin\x64\)

Then type "powershell -ExecutionPolicy Bypass -File .\CPAVXPatcher_v1.ps1" (without quotes) and press Enter


cd c:\Program Files (x86)\Steam\SteamApps\common\Cyberpunk 2077\bin\x64\

powershell -ExecutionPolicy Bypass -File .\CPAVXPatcher_v1.ps1


Enjoy!


If at some point you experience an AVX crash, please upload crashdump to the Nexus Fashion page as an error message so that I don't have to recreate the same script on my computer. If I have your crashdump, it will take ~15 minutes to update the patch script and release a new version to fix the crash!

Crash dumps are stored in C:\Users\[your username]\AppData\Local\REDEngine\ReportQueue\

Open the desired folder and upload the Cyberpunk2077.dmp file to the bugport.


Be healthy!


TL;DR

Extract CPAVXPatcher_v1.zip to the Cyberpunk 2077 installer where Cyberpunk2077.exe is located

Run Windows PowerShell as administrator

Type powershell -ExecutionPolicy Bypass -File .\CPAVXPatcher_v1.ps1 and press Enter
