AMD today came out firing guns to remove all reports of performance regression on its Ryzen 7000 when running Windows 11. Those reports came from experienced independent testers who said they were seeing less-than-optimal performance on newer Zen 4 CPUs, typically on the new Windows 11 Feature Update 22H2. AMD says it tested those claims and found nothing of substance, as performance on Windows 11 and Windows 10 was well within typical error margins.

The company writes:

We have received reports of unexpected performance deltas in certain games with AMD Ryzen™ desktop processors, as well as performance variations between Windows® 11 and Windows® 10 in certain game titles. We are currently investigating, but based on testing to date, we have not observed a substantial difference in game performance between OS versions across a variety of operating scenarios and game titles.

Furthermore, he believes that the observed differences may have to do with the game optimizations themselves and not something AMD messed up on their end. He says:

Many factors affect game performance, including game engine, CPU architecture, GPU selection, and memory options. As new architectures enter the market, we often see performance anomalies that need to be addressed by the component vendor or game publisher. This is not a new or unexpected phenomenon.

So what AMD is essentially saying is that future optimizations for Ryzen 7000 and the Zen 4 architecture will likely fix these performance issues. For those who missed it, reports indicated that disabling SMT turned out to be more useful, especially in cases where fewer CCDs (CPU Compute Die) are implemented.
