Well, it is not a piece of news that bugs and performance issues have plagued cyberpunk 2077. But rumour has it that AMD Ryzen owners now have an unofficial performance patch for this issue. The patch recently popped up on Reddit, enabling proper SMT support and boosting minimum framerates.
According to sources, a compilation issue caused Cyberpunk 2077’s executable not to recognize logical cores on AMD systems with SMT enabled. Thus the game ran with multithreading disabled and resulted in major framerate dips in CPU-intensive areas.
The patch provider, who goes by the name u/UnhingedDoork, pointed out that this issue could be resolved by simply replacing one line of hexadecimal code in the game executable. The guide shared by the developer is given below, but do note that it only works if you’re running an AMD Ryzen CPU. This does not affect Intel CPU owners.
1.) Download and install a hex editor such as HxD from here.
2.) Open up the Cyberpunk 2077 game executable in HxD (make sure to open the game’s actual executable, not the one for RED Launcher).
3.) Click on the Search tab, then click on Replace. Search for this line of hex code: 75 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08.
4.) Replace it with this line: EB 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08
5.) Save and close HxD. The next time you launch Cyberpunk 2077, set the game to windowed mode, then open up your Task Manager.
“Cyberpunk 2077 is an open world, narrative-driven role-playing game set in the universe of the classic pen & paper RPG system — Cyberpunk 2020. The game follows the story of V — a hired gun on the rise in Night City, the most violent and dangerous metropolis of the corporate-ruled future.”
