Microsoft’s first Windows “11” update addresses AMD CPU scheduling problems. Ends up making them worse.

Microsoft released their first “Windows 11” update.

It was deployed to try to correct the AMD CPU problems that Windows “11” created on Ryzen, which tripled L3 CPU cache latency and slowed the processor down by an average of 15%.

The update ended up making the problem worse. Doubling the cache latency from where it already was at launch.

“Early adopters” of Microsoft’s latest broken operating system are seeing much worse performance than they were on Windows 10, even on the Intel side, as Microsoft’s “virtualization based security” was already wreaking havoc on video game performance.

Microsoft trimmed the list of supported computers to only about the past three years worth of CPUs and still can’t even support this properly, while the Linux kernel still runs on CPUs from a decade or two ago as well as can be expected within the limits of the hardware itself, and runs great on my Tiger Lake Core i7 too.

If Microsoft can’t figure out CPU scheduling, maybe it ought to just give up pretending it has a viable operating system.

Instead of covering the broken CPU scheduler mess (part 1 or 2), PC World went on to quote Microsoft that the updates were 40% smaller, which should be a relief to people running Windows, since Microsoft uses their computer as part of a botnet to deliver these updates to strangers over the internet.
