A new Cyberpunk 2077 performance mod addresses various performance issues on PC including AMD SMT usage.

Created by ‘Yamashi’, this new modification fixes several performance-related issues, the most important one being related to Simultaneous multithreading usage on AMD CPUs.

According to ‘Yamashi’, users who are GPU-bound will not see a performance increase in their average FPS, but there should be fewer FPS drops.
