AMD states in its statement that they are aware of the performance differences in certain games. The company also states that they have received reports that certain games offer different performances between Windows 11 and Windows 10, but based on the tests made to date, they have not observed a significant difference in game performance between operating system versions.
The problem is due to optimization
AMD says it’s investigating all these issues and is in touch with both manufacturers and developers. It is stated that the performance problems experienced are nothing new, and that there is always an early optimization problem with new processors or graphics cards.
Finally, we can say that such problems are really experienced in new products entering the market. When the developers provide the necessary optimization to the game engines, the performance balance between the processors will be in place. However, these optimizations will take some time.
