AMD Ryzen Branch Prediction Optimizations Now Available to Windows 11 23H2
AMD announced that its Ryzen processor branch prediction optimization that provide gaming performance uplifts, is now available for Windows 11 23H2, through an optional update. This update applies to AMD Ryzen processors based on the "Zen 3," "Zen 4," and "Zen 5" microarchitectures, and essentially yields the kind of performance you get in the real Administrator account, on regular Windows accounts, especially non-local (online) accounts. Users should look for "Cumulative Update Preview for Windows 11 Version 23H2 for x64-based Systems (KB5041587)" in Windows Update, which should begin showing up as an optional update. This update requires a system restart to apply.
With this update in place, gaming performance uplifts between Windows 11 23H2 and 24H2 should be identical. "We wanted to let you know that the branch prediction optimization found in Windows 11 24H2 has now been backported to Windows 11 23H2. Users will need to look for KB5041587 under Windows update > Advanced options > Optional updates. We expect the performance uplift to be very similar between 24H2 and 23H2 with KB5041587 installed," AMD said in a statement to Wccftech.

I encourage anyone to look up what branch prediction is before thinking it has anything to do with being an "Admin".
this stuff makes these threads super active so I get it but damn.
Though that doesn't matter since it only seems to use the 8 wide dispatch on zen 5 while running two threads through a core. While it seems a single thread it still uses 4 wide dispatch and a single predictor. Eventhough techinally zen 5 should be able go use both on single thread.
The crime here is the rewrites that 24H2 implemented taking so long to reach users.
Stop making statements about things you know little or nothing about.
Weirdly enough the scores kept creaking up on the 3 runs with the last one bing the highest.
It said it was already installed on my 23H2 win, perhaps it's included in the latest cumulative update
Running as sys Admin / Root bypass the VBS issue, this is why there are some gains on 23H2 doing that.
Also some early testing shows that 23H2 is still slower than 24H2 after this patch. At lease for these games the patch did F'k all on 23H2, at least for this guy's set up.

When will it be debloated and optimized by Microsoft themselves ?
It sounds to me like this is basically a bug fix that allows accounts that are not the built-in administrator to use the right branch prediction optimizations, sounds like there was something preventing the AMD optimizations from being used with other accounts.I'm guessing sometime between when hell freezes over and never. The bloat is one way they monetize the OS. I suppose they could remove it and pass on the revenue loss to the consumer in the form of a more expensive OS....
They pulled the same thing with XP 64, original Xbox and every Windows release after AMD released Ryzens with multiple CCDs.
Go Linux!
if a Mercedes sucks out of the factory but is only a decent car after it’s tuned by brabus for an additional couple of hundred thousand dollar the original car isn’t a good car.
you even need to have the hundred thousands worth of modification done again after filling it car up with a fresh tank of gas which is what happens when you update to a new feature release.
windows 10 and 11 are a horrible intrusive mess people put up with because they have to
