GPUOpen Code Hinders AMD CPU Performance on Cyberpunk 2077 (Updated)
This article originally was based on the assumption that Intel’s Compiler was the source of performance issues in Cyberpunk 2077. We have updated the article to reflect the fact that the real source of the issue is GPUOpen. The initial report used the information available at the time.
The amount of performance you can gain isn’t certain at this time, however Redditors are reporting double digit gains in performance for average and/or minimum framerates. If you’re willing to do just a little hex value editing, then there’s some free performance for you. However, you should apparently use the proposed change in this comment as other proposed changes could be worse on Intel CPUs. EDIT: Note from Editor, it has come to our attention that not all users are reporting performance increases. Some are reporting higher utilization with no effective change in performance, while others are reporting performance decreases.
It also isn’t clear why CD Projekt Red didn’t optimize for AMD CPUs. This seems to be a simple oversight; the one specific part of the GPUOpen code which causes the performance issue relates to a check on whether or not the CPU is of the Bulldozer architecture, one of AMD’s most infamously poor architectures. Even today, Bulldozer haunts AMD users. Hopefully CDPR fixes the issue ASAP.
