Ryzen 7000 and 9000 see massive gains from Windows 11 24H2. Mostly.

Seeing a big lift in CB R23 nT on my 5800X3D. Of course, a sample size of one on each test where results can vary. But both were done with the same conditions.

I've seen a few sources that benchmarked Windows 10 against 11 23h2 with the patch and 24h2. Few takeaways - 24h2 seemed to make no difference in many cases unless they did fresh install from iso instead of just upgrade in place. Not always the case but worth keeping in mind. 23h2 with just a patch is still a bit slower than 24h2 in many cases. Windows 10 performance without any fancy patches is about the same as 23h2 with a patch - seems Windows 11 has been slowing down Ryzen CPUs, but Windows 10 hasn't been, yet 24h2 adds something a bit extra in comparison to just patch for 23h2. Likely why many people never noticed any issues earlier, as they still use Windows 10. Also, all the benchmarks were done with vbs on (and in general default settings on current versions) on all systems, so that's not part of the problem.

Some of us prefer the extra security of VBS and will take the hit. I've seen very little difference on my 3900X in games and a tiny difference in Cinebench.

Also, I may as well add this:

24H2 fresh install vs 23H2 fresh install here is one of the reasons for the performance jump:

Interesting, I cursory benched 23H2 vs 23H2 with KB5041587

After enabling virt in BIOS & VBS the CoD bench I ran in that thread is almost exactly the same as pre-patch, i.e. If you enable VBS after applying KB5041587 in Win11 23H2, at least on my era of CPU there's no penalty. I suppose I'll take that.

That's fair, but it's still putting lipstick on a pig. If you _really_ cared about security for yourself, are you even using the right platform with the identities that are important to you? If it genuinley means that much to you don't use your important identities on a general purpose/entertainment/gaming PC. Use a Chromebook for personal affairs, use a PC for entertainment with identities you couldn't care less about.

I'm not saying your making bad choices, I'm saying that the type of threat & threat actor that VBS mitigates against have bigger fish to fry, especially if all they'll be able to own are you're entertainment credentials.

As far as I know HWUnboxed always test with VBS off (and they check that it's off), so I doubt it has much to do with the performance increases in their testing. I can see where you're coming from, but in my testing on my PC and in the games I play the difference was tiny so I kept it on. If the difference were much larger then I would probably have a different opinion.

There are degrees of security though, it's all about making sure your machine is not among the low hanging fruit and I like how VBS works to mitigate a number of potential zero day threats (some such threats can be invisible to the OS and almost impossible to remove if you are infected). Also, there is no such thing as a perfectly secure system.

I have tpmf or whatever its called turned off in the BIOS, is that why?

Are you using Intel or AMD? It's SVM for AMD and I believe it's VT-x for Intel.

I would enable the TPM if that's what that tpmf setting is (if you don't have a discrete TPM that is).

fTPM is AMD and generally disabled to stop some game stuttering but this is needed to install Win 11 though can be disabled again after install.

I'll look for that in the BIOS later thanks...
