Dear CD PROJECT RED, I was so certain you would do this - not pay attention to your original minimal CPU requirements - and I was right. With the installation of the next-gen patch, the loading screen in the game does its loading for a while and then crashes to desktop reliably. The crash handler does not produce a helpful explanation, but my debugger does.
Unhandled exception at 0x00007FF6F3885B26 in witcher3.exe: 0xC000001D: Illegal Instruction.
The instruction in question is AVX512
00007FF6F3885B26 vcvtps2ph mmword ptr [rdi+rdx*8+8],xmm1,0
which my CPU does not have. It's a Phenom II X6 CPU and it used to be able to run the game quite well! It is still listed as the minimum CPU required to run the game on Steam. So this next gen patch remotely bricked a game I used to be able to play. Please have a heart and help out a gamer with an older computer.
