Windows 11 is formally out, however in case you’ve acquired an AMD Ryzen processor, you would possibly wish to maintain off on updating for a bit: the company is reporting that its chips might need points with the brand new OS that might trigger efficiency drops of as much as 15 p.c in some circumstances.

AMD and Microsoft have discovered two essential points with Windows 11 on Ryzen. The first is that Windows 11 could trigger L3 cache latency to triple. AMD says that the problem might trigger 3–5 p.c worse efficiency in most affected purposes, whereas some video games (AMD particularly calls out these “commonly used for eSports”) might see efficiency dips of 10–15 p.c.

Windows 11 can also be having points with AMD’s “preferred core” technology, which often goals to shift threads over to the quickest core on a processor. AMD warns that customers might see efficiency points on CPU-reliant duties, particularly on processors with greater than eight cores about 65W TDP.

AMD and Microsoft have already confirmed that they’re “actively investigating these known issues for resolution via software updates.” The two firms promise that each a Windows replace and a software program replace are deliberate for later this month to attempt to resolve these points. But within the meantime, you would possibly wish to stick to Windows 10 till AMD and Microsoft type issues out.
