AVX Bypass
AVX Bypass
Simple hex edit of the Cyberpunk Client to bypass AVX instructions check that causes crashing on some machines.
Cyberpunk 2077 Version 1.04
Just a simple hex edit to bypass the AXV instructions check that causes Cyberpunk 2077 to crash on some machines.
This change allows the game to run on older CPUs (Pre-2011) that are missing the Advanced Vector Extensions.
[Actual change is just changing hex value “554881ECA00000000F2970E8” from the official .exe with, “C34881ECA00000000F2970E8.”]
Instructions:
Open your Cyberpunk 2077 folder.
[Cyberpunk 2077 -> bin -> x64]
Backup Cyberpunk2077.exe
[Simply renaming it to Cyberpunk.exe.bak will do.]
Rename this file to Cyberpunk2077.exe
[You may skip this step if you don’t mind running the executable directly.]
Special Thanks:
Thanks to FrostedHedgehog for finding the fix.
Thanks to Maks13372281337 for posting the premade fix for 1.03
Notes:
Was getting very frustrated for the game being unplayable due to the AVX crash, and was happy to find the original AVX Fix posted on Nexus.
Then 1.04 rolled around and made that fix obsolete at the time, so I looked into doing it myself. And since it worked, I figured I’d post it for anyone else who has the issue who may not be inclined to hex edit it themselves.
Hopefully it helps others to be able to jump back in game with less of a headache. Happy gaming.
