On October 5th, Microsoft finally released the official version of Windows 11. Although Windows 11 is called “one of the most important version updates in 10 years” by Microsoft, to be honest, Windows 11 is still a bit disappointing.
Regardless of the features and practicability of other new features of Windows 11, take Microsoft’s official claim that “Windows 11 will bring users the best gaming experience ever” as an example, users have been “faced” in the past few days.
AMD and Microsoft recently announced that compatible AMD processors may experience performance degradation in certain applications when running Windows 11. Specifically,After installing Windows 11 on AMD processors (such as its EPYC and Ryzen series), performance may drop by up to 15%; The size of the impact depends on the running application, which has the most serious impact on the game.
Although it has not been listed on Microsoft’s Windows 11 Known Issues table, AMD has officially admitted that there will be performance degradation when running “certain applications.”
One of the biggest problems, L3 cache latency increased by about 3 times. AMD gave a more detailed explanation on this: “Which applications that are sensitive to the access time of the memory subsystem may be affected; the expected performance impact of the affected applications is 3-5%, and 10 may occur in common e-sports games. -15% abnormal value.” It is reported that the latest Windows update package expected to be released in October 2021 will solve this problem. At the same time, AMD officials also advise affected customers to postpone the Windows 11 upgrade.
However, on October 2nd, before the official version of Windows 11 was released, Microsoft officially posted on its Twitter account that “FTW technology response technology that puts high-performance games in the first place.”
Soon after the tweet, a netizen asked: “Unless you are running an AMD chip, right?”
In addition, Windows 11 has also been exposed before, the new Windows 11 memory protection function reduces the frame rate of some games.
According to a report by UL benchmarks, the well-known graphics performance testing software 3D Mark development company, claimed that after a series of tests, it found Microsoft Virtualization-Based Security (Virtualization-Based Security, VBS for short) built into the Windows 11 system. Function, it can reduce the game performance by up to 30%.
The UL benchmarks company pointed out in the test: “A feature called Virtualization-Based Security (VBS) leads to a decrease in game performance. VBS is enabled by default after installing Windows 11, but it is not enabled when upgrading from Windows 10. This means the same system. Different benchmark scores can be obtained, depending on how Windows 11 is installed and whether VBS is enabled.”
Microsoft officially stated that VBS has greatly increased computer protection measures to protect it from vulnerabilities in the operating system and prevent attempts to block some malicious vulnerabilities.
Finally, UL benchmarks company hopes that Microsoft can optimize this feature more, or disable this mainly enterprise-centric security feature by default.
