If anyone with an older CPU finds that Cyberpunk 2077 crashes on the load screen now, don’t waste time trying different wine runners… it’s AVX instructions that crept in again. Find something like this in the output (e.g. start lutris with -d). There’s a lot more in the back trace, but it’s pointless to post a register dump in this circumstance.
It involves using a hex editor on Cyberpunk2077.exe to search for strings and replace them. He notes one of them as having to be changed in 3 places, but there are others that exist in 2 places that he didn’t note (and yes they are the instruction, not just random matches).
If anyone wanting to attempt this is unfamiliar with a hex editor, no, you don’t put the “h” in the string “90909090909090h”, you replace the bits with 90. The h is just to denote (to you) that it’s hexadecimal notation.
It did not take me very long, and now my game loads again (program still runs, game loads and worked OK for several minutes before I quit).
I am using lutris-6.14-3 and DXVK v1.9.1L and it’s working pretty well.
