Game crashing on old CPUs: possible fix
If you happen to have an old CPU you maybe having this crash:
Expression: EXCEPTION_ILLEGAL_INSTRUCTION (0xC000001D)
The game is trying to use a feature you don’t have: AVX.
At the beginning playing corpo when you sit it crashes. A possible temporal solution while they fix this issue is to remove this part of code:
Edit Cyberpunk2077.exe with a hexadecimal editor and search for
Change the first byte to C3 (return from the function):
Please note this fix is extremely simplistic and naïve. Moreover, it could crash the game later. This change seems to fix this crash and you can continue playing the game. I have only tested a few minutes more.
FAQ: Why are they using AVX?
They are not doing it on purpose, it is probably the default configuration of the compiler.
I'm on steam - same issueI am having the same. For nomad, I get to the Night City cinematic, then after, it crashes 100%. For Street Kid, it is trying to leave the bar. Same sit situation for Corpo. Did all the tshooting they said too. Seems like a patch requirement for gog. Homies on steam and consoles are fine.
Same here, Corpo campaign "sit down V" instant crash 100% of the time.Exact same spot as me when I tried corpo. So pretty consistent between a lot of people it seems - means hopefully it is fixable soon!
