ReviewsTipsWindows 11 bugs decreasing performance in computing: Upgraders better wait

According to the company itself, performance can decrease by 3 to 5% in common applications, with a drop of between 10 and 15% in "games commonly used for esports". That's not good news, considering that multiple AMD chips are used on gamer PCs - including streamers and professional players.

Windows 11 was released by Microsoft last Tuesday and is experiencing some serious bugs since then. Errors in Oracle virtual machines, high memory consumption, bug in mixed reality devices and crashes in the new Far Cry 6. Now, it was AMD’s turn to release a statement talking about a possible performance drop of its chips in the new system.

According to the company itself, performance can decrease by 3 to 5% in common applications, with a drop of between 10 and 15% in “games commonly used for esports”. That’s not good news, considering that multiple AMD chips are used on gamer PCs – including streamers and professional players.

In the statement, AMD said it is investigating the bugs along with Microsoft, with the goal of releasing updates that resolve the issue as early as October. Of course you also have the option to wait to upgrade your PC to the new system.

What’s going on with Windows 11 and AMD chips?

The AMD announcement provides a table with the complete explanations (and in very technical jargon) of what are the failures that cause performance to fall on Windows 11 PCs.

In short, there are two problems.

  1. The first and most worrisome is an increase in L3 cache latency. This means that the CPU takes longer to access the data in system memory, which can be a problem in online games that don’t require as much power in the graphics, but require a lot of memory – such as DotA. This is what AMD talks about when it comes to “games commonly used for esports”. Then a 3% delay can make a difference. Imagine a 15% performance drop!
  2. The second problem is the core management of AMD processors, which is not directing applications to the fastest cores as it should. This issue affects performance more on machines with 8 or more cores, but can cause a fall in frame rate per second on other AMD-eat PCs.

Several CPU models are being affected by these bugs in the 2000, 3000, 4000, and 5000 series, as well as some EPYC chips used in data centers. AMD drivers must be updated by the end of the month to resolve all of this—but there are a few things that depend on an update from Windows itself. For now, the factory itself recommends that customers continue on Windows 10 even…
