AIDA 64 has tested both the Microsoft update to Windows 11 and the AMD chipset driver update. Agrees that they seem to work.

Definitely works on my Ryzen 7 4800H based laptop. Before the update and chipset driver update, it felt clunky and jerky now it feels smooth and fast again.

Cheers, just got my mum an AMD laptop and then this latency nonsense comes out... she'll click on the "upgrade to Windows 11" button at some point, I'm sure.

Meant to disable TPM when I was there last to prevent any forced or accidental upgrades. When I was setting up the printer I got nagged at least 3 times from various sources.

Got to be honest never noticed any slow down on my 5500u laptop but stuck both fixes on.

Hardware Unboxed (Youtube channel) reported some blue-screen crashes after Windows 11 upgrades, but none after a fresh install, so possibly better to do the latter if that's an option.

I'm due a fresh install at some point so I'll have a look when I get back home next week, not decided if I'm going to stick with 10 or move to 11, there doesn't really seem to be any compelling reason to shift like there was with going from 8-8.1 for instance..

Agreed. I'm not seeing one either.

All the way from announcement to arrival, I was thinking "10 was the 'last ever' version, so to bring out a new version, they must be waiting to spring some big surprise, some reason to justify a new version number". And .... nothing. Well, I suppose the heavy restrictions on compatible machines was a surprise, but not a good one. In terms of user functionality, 11 strikes me as more of a 10.1, though that compatibility issue may well be why MS, for their own strategic reasons, decided to draw a clear line in the sand. And if so, I like what might be inferred from it even less.

So no, no compelling reason for me either. Not anything at all I care much about, TBH.

Along with the recent chipset drivers from AMD, this update does seem to have made a difference. AIDA64 now reports anywhere from 10.5-12.5ns for CPU L3 Cache latency. Prior to the update, I was seeing 20-30ns. That's on a 5900X on an X570 board.

What were you seeing under Windows 10?
