Windows 11 decreases the performance of AMD processors

AMD warns of bad performance on Windows 11

AMD has warned of decreased gaming and application performance on Windows 11 computers running on its processors.

In a new tech support document published on its website, the chip manufacturer said there were two known performance changes that its Windows 11 compatible AMD processors might exhibit in specific applications.

Amd warns of worse performance on windows 11

 

[Conack]

So Microsoft engineers decided to build Windows 11 on an Intel testbed - in short. Gotcha.

 

[Crowley]

Still faster then Intel.

Isn't this already known, and mostly applicable to Dx9 titles?

 

[Fulcrum29]

Known from back in August already,

Why not. I don't mind deranking...

Besides, the Microsoft patch for this is expected this month already, though by how much the situation will improve, I don't know. Really, Dx9... the performance hit would hardly hit you 'online'.

weird, I have a 5950X and I have experienced the opposite. I have gained about 10% single-thread performance.

For the first time, the scheduler is selecting the higher quality cores.

wonder if motherboard BIOS has something to do with it.

[Vrotappel]

Would it not be more apt to say AMD processors decrease the performance of Windows 11?

 

[Sapphiron]

Dx9 titles?

Mostly DX12

Mostly DX12

AMD chose their wording well,

Measured and functional L3 cache latency may increase by ~3X

• Expected performance impact of 3-5% in affected applications, 10-15% outliers possible in games commonly used for eSports.

the issue is well explained in the LTT video, but it is for the most part CSGO which is affected. I would believe that the affected application must be a handful of products, most of which are 3D accelerated I believe.

Had a bit of an issue today after upgrading my Ryzen 1700 rig to Win 11. Watch Dogs 2 started stuttering and lagging, but a quick driver update fixed it and it ran normally after a restart, so I can say that although I did not specifically measure perfornance, Win 11 feels much more responsive than Win 10.

Exactly. How did this pass beta testing?
Surely this should have been tested on the Beta release.

 

[Arthur]

Exactly. How did this pass beta testing?
Surely this should have been tested on the Beta release.

Of course the claim that it wasn't tested on AMD is utterly preposterous.

Windows 11 is a beta release. /runs

If I recall correctly we had the same issues with Windows Me. It ran fine on Intel's hardware but anything else was hit and (mostly) miss. XP of course Blue Screened on a lot of platforms. Who remembers Tomato Motherboards? I was a much happier techie when SP1 and SP2 were released.

Pretty much all software release are beta releases these days.

I think Ill hold off on this update until the tech is mature enough not to have these kinda bugs.
