AMD problems with Windows 11 solved now?

[teletom 98]

Guys, pop up just appeared on my PC that Windows 11 is now available to be installed.

What is the latest on the peformance problems regarding AMD CPUs (in my case a 5950x) and Windows 11?
Should I give it a go or ignore it .... PC mainly used for MSFS 2020.

Cheers, Tom

I have a 5900x .. saw the pop up .. waved it off for now. Until i see a tangible reason for upgrading im good with what is proven to work. 

 

but if you insist on upgrading

No, not insisting ... just curious about the current status of the subject and opinions of people that have been brave enought to try it.

Issue has been solved some time back. I’m running Win11 with a B550 MB and 5900x and am having no issues. Just grab the latest BIOS version, chipset drivers and Win11 updates and you’ll be fine.

The initial problems with preferred core, cache coherence and L3 cache performance have been solved. I get equal/better performance in Win11 as I did in Win10.

There's however a bug that affects some users where the TPM causes hickups/lag when enabled. This happens regardless of the OS, but since TPM is required for Win11, more people are experiencing it on Win11. A BIOS fix is expected around April.
