Windows 11 began to develop this week after just over three months of public testing with Windows Insides. While the operating system has been introduced with a few known problems, it seems to have gotten undetected. AMD has confirmed that its Windows 11 upgrade process will be negatively affected, in some cases, with reduced effects. Thankfully plans are already on the way.
AMD has two distinct problems with its processors and points to Windows 11. First, it has to do with the hidden L3 cache of its processors, which can only be three times higher in Windows 11. This mainly affects the performance of apps that depend on temporary access to the memory subsystem, including some equipment titles pace quickly. AMD says performance is up to 15% on specific sports, but mostly between 3% and 5% of completed performance ranges.
For this one, AMD says it’s going to be shooting for the Windows 11 update later this month, with patch Tuesday updates next week. This will be the first cumulative update for Windows 11 with its general posture, we should see a copy of the bug fixed alongside this one.
The other problem is with the feature “preferred core” in UEFI systems not scheduling functions for the core as quickly as possible in sending data. This affects the performance of most applications that rely on one or a few kernels, while multi-stairs work on all available cores anyway. As such, the performance can mean more impact on processors with core and thread counts, especially with 65W TDP or higher. AMD does not explicitly say how big the performance impact is.
Regardless, even in the works of this problem it is a myth. AMD says it will arrive with a “software update”, not a Windows update, as in the form of a new driver release for Windows 11. This fix is still expected this month.
Windows 11 runs on step by step, and although it is likely not upgraded for many users, it shouldn’t be a huge issue. It’s not unheard of for major new problems to arise after new proposals this way, and at least the schedule is coming up relatively quickly. We also heard an issue with Virtualization-Based Security potentially affecting game performance, which is now being investigated by Microsoft. If you haven’t already, read your Windows 11 review to see why we recommend the upgrade to anyone using Windows 10.
