In a statement released via Twitter, CD Projekt RED promises to fix bugs and crashes via a series of updates. A new patch is expected within the next seven days and there will be two more patches in the coming months one in January and another big one in February.
Interestingly, it appears CD Projekt RED didn't test the game properly on AMD Ryzen CPUs. Various media are reporting that Cyberpunk 2077 doesn't use multi-threading on AMD Ryzen processors. Some users managed to figure out a quick edit to enable SMT on AMD processors, this requires you to edit just a single string with a hex editor:
User UnhingedDoork provided a quick solution to this problem, which appears to improve multi-threading support by the game, and as a result, increase minimum and average framerate and overall gaming experience. The solution requires a modification in the game executable file, which appears to affect how the game recognizes the CPU. Do note, it has nothing to do with kernel optimization for Intel.Making this change will result in higher framerates on Ryzen-based systems.
