Windows 11 Fails – Update makes AMD performance even slower

After it came to light that Windows 11 was causing performance problems for computers running AMD processors, Microsoft updated its new operating system… and made things worse.

According to TechPowerUpThe latest cumulative update for Windows 11 released on October 12 has increased the latency of the L3 cache, which has a direct effect on the performance of some games. Meanwhile, another issue pushes threaded workloads to the faster core of a Ryzen processor, which could also affect performance on CPU-dependent tasks.

TechPowerUp testing found that prior to the update, Windows 11 running on a PC with a Ryzen 7 2700X CPU had a latency of 17 nanoseconds, while it typically exhibits 1ns latency. But after the update, the same tests now see a latency of 31.9ns.

A patch is in the works, and AMD plans to release a fix for this issue on October 21. Some “customers” may request to get the patch earlier, but this may only apply to enterprise-level customers.

However, Microsoft will release a patch on October 19, which is scheduled to fix the L3 issue. But it is very likely that the key patch that will be obtained is the one from AMD.

As such, if you’ve been considering getting an AMD Ryzen-based PC, like the ones featured on our Best Gaming PCs list, with the explicit goal of owning a Windows 11 machine, you may want to keep the fire going. The same is true if you plan to upgrade your AMD Ryzen PC from Windows 10 to Windows 11.

While Windows 11 has only been available for a little over a week, its release hasn’t been very smooth. Not only have there been concerns about Windows 11 TPM requirements, but there are plenty of Windows 11 bugs that have caused user problems, although these come with some easy fixes.

One way around this problem is to check out our pick for the best Windows 11-ready laptops, although they may not be ideal for people who want the best gaming performance.
