This is a patch script that'll remove all known AVX instructions from Cyberpunk 2077 v1.3

Unpack the files into your game installation, where Cyberpunk2077.exe is located.
e.g. c:\Program Files (x86)\Steam\SteamApps\common\Cyberpunk 2077\bin\x64\ (Steam. GoG has different path but works fine as well.)

When unpacked start a Windows Powershell with Administrator rights and run these commands.
cd c:\Program Files (x86)\Steam\SteamApps\common\Cyberpunk 2077\bin\x64\ (or the path where your game is installed?)
powershell -ExecutionPolicy Bypass -File .\CPAVXPatcher_v1.ps1

Enjoy!

If you encounter an AVX crash at some stage, please upload the crashdump to the Nexus mod page as a bugreport so I don't have to recreate the same scenario on my computer. If I have your crashdump it takes ~15 minutes to update the patch script and release a new version fixing the crash you encountered!

The crashdumps are stored in C:\Users\[your username]\AppData\Local\REDEngine\ReportQueue\
Open the correct folder and upload the file Cyberpunk2077.dmp to the bugreport.

Be well!

TL;DR

Unpack CPAVXPatcher_v1.zip into your Cyberpunk 2077 installation, where Cyberpunk2077.exe is located
Start a Windows PowerShell with admin rights
Type:

cd c:\Program Files (x86)\Steam\SteamApps\common\Cyberpunk 2077\bin\x64\ (or the path where your game is installed?)
powershell -ExecutionPolicy Bypass -File .\CPAVXPatcher_v1.ps1

Done!
