Windows 11 experienced its first “Patch Tuesday”, where Microsoft releases patches fixing issues on the second Tuesday of every month. This time around, many expected that the patch would include fixes for an issue with Windows 11 that could increase the gaming performance of AMD processors by up to 15%. However, this did not fix the problem, and it may have made the situation worse.
techpowerup report That October 12 Windows 11 patch nearly doubled the Ryzen 7 2700X’s Level 3 (L3) cache latency. This is the lowest level cache on your processor, which stores the streamed data from your RAM before sending it to the higher level. According to AMD, the increased latency can result in a frame rate drop of up to 15%, especially in esports titles.
As for the specifics, TechPowerUp says it went from an L3 cache latency of 17 nanoseconds on Windows 11 to 31.9ns after the patch. The first result is already well above the 10ns cache latency that the chip should have, making the jump even worse with recent Windows updates.
The good news is that a fix is on the horizon. on reddit, u/destiny2sk shared an image Showing the release date for patches that fix problems with Windows 11 and AMD processors. According to the post, Microsoft will release a patch that fixes the cache latency issue on October 19, while AMD will release a patch for a different Windows 11 issue on October 21.
We weren’t able to track down the original post, so these dates may not be accurate. However, AMD has confirmed that both the issues are expected to be resolved in October.
Windows 11 is off to a rocky start. The operating system caused a lot of controversy when it was announced due to its strict CPU and TPM requirements. Now that it’s here, we’re hearing about all kinds of Windows 11 problems, from slow gaming performance on AMD chips to a nasty memory leak bug.
As TechPowerUp notes, these issues are important not only for AMD users, but also for the upcoming launch of Intel Alder Lake processors. We’ve heard a lot about Thread Director in this new generation, which reportedly improves performance when paired with Windows 11. If these problems are not addressed soon, AMD could enter the battle at an immediate loss.
