It would be very strange if a large information of Windows όπως τα Windows 11 δεν προκαλούσε σημαντικά προβλήματα. Τα Windows 11 έκδοση 21H2 ή Build 22000.194 φέρεται να προκαλούν σημαντική επιβράδυνση της απόδοσης, προβλήματα στο διαδίκτυο και μια σειρά από άλλα προβλήματα σε ορισμένους users.
Although there are benchmarks that showed that Windows 11 is slightly faster than the Windows 10, AMD confirmed the slowdown of its systems.
AMD and Microsoft are investigating reports of Windows 11 performance issues, according to a support document released by AMD, Windows 11 could reduce the performance of some applications.
According to the document, the latency of L3 cache can be increased three times, which could affect the performance of applications that require memory. AMD expects a 3-5% performance impact on some applications, while games could be slowed by 10-15%.
Microsoft plans to address these issues in the next cumulative update.
Another Windows 11 bug seems to be compromising performance by ignoring CPU threads. AMD has noticed that applications that are sensitive to CPU threads may experience performance issues. These problems are obviously noticeable after updating the machine, but not all installations seem to be affected.
“Impact on performance can be more detectable on> 8-core processors over 65W TDP. "A software update is underway to address this issue." he says AMD.
If you're using Windows 10, it's a good idea not to upgrade to Windows 11 version 21H2 (initial release) until Microsoft fixes or at least offers a solution for these performance issues. If you're already having problems, AMD recommends you wait updates software from AMD and Microsoft.
In addition to AMD, benchmarking company UL Procyon has confirmed that a feature in Windows 11 called "Virtualization-based Security (VBS)", which is now enabled by default, is causing performance to drop. Thus, the benchmark scores are slightly lower when comparing Windows 11 version 21H2 with VBS enabled.
To turn off VBS follow these steps:
Open Windows Search.
Look for Core Isolation to open Windows Security.
Disable Memory Integrity and restart your computer.
Open Registry Editor (regedit) and follow the path:
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ DeviceGuard
Double-click EnableVirtualizationBasedSecurity and set it to 0.
