Get Process Lasso and run your game only on P-cores. For some games, HT on P-cores helps, for others it doesn't. That's why you need to test it, and the best way to do that is with CapFrameX.
intel thread director it's already built into windows 11 and works directly and automatically with the windows scheduler.. that's why most of the issues with 12th, 13th and 14th gen of intel cpus were on windows 10 or early versions of windows 11.
Since when?
If you want custom optimization, there is always room for it.
More cores, worse scheduling and/or prioritization >>> higher consumption and latency = lower FPS (in overall)
You can try disabling HT on the P-cores so that only the P+E cores remain, and check if your FPS improves in some games.
Since always partially, the hardware part of intel thread director was designed and introduced with alder lake with windows 11 in it's heart, it does have support with windows 10 but doesn't work as good as it should, with the first iteration of windows 11 it also worked but still with minor flaws as we all know windows 11 was full of issues at launch. IIRC was from 2023 23H2 with the updated Intel Thread director "TD2 Update". that started to work with excellent results, and a bios update was required for Alderlake CPUs as it came updated from raptor lake and newers, also thread director received a major update to mobile with lunar lake.
I can only wish you luck in the hope that the scheduler will work as it should.
Intel for server cpu made to be more run on Linux are way more homogenous in their cores config than the workstation that has more chance to run windows segment, I think one reason for the server type is that they run more homogenous workload, so you know in advance which cores are better for it and just buy those (and predictability of performance can be major has well). And matching program name could become quite optimised for an hyper scaler work.
Lot of linux use heteregenous cores on the mobile space and Linux like Mac on the PC space, samsung as big-middle-little, as for server workload not available to Linux developper (i.e the intel, amazon,meta, microsoft, ibm, google) I am not sure what that mean ?, the people making server workload and making linux tend to be the same peoples, lot of server monitoring need to be ran on the same core than the task, having one of 128 cores being smaller because it monitor the rest of the does not need to be on the cores, gain to be on CPU would not be worth the complexity. On laptop it is quite different (laptop is a lot what driving PC intel cpu direction and decision)
Have had ecores disabled for a while now and I find the hyper threads gimmicky especially since I tested them against the E cores which were about probably 40% faster than the hyper threads for me personally the juice isn't worth the squeeze of the hyper threads to add so much heat and voltage adding discomfort heating up my room differences maybe a percent or two certain games but definitely not the ones I play so it's permanently off for me yea.
I can show you just this:
I'm not sure if we're using the same CS2 benchmark (as in the video), but as you can see, CS2 relies very heavily on DDR5 tuning and, to some extent, on the processor clock speed.From linked video:

14900KF P+E + 4070 ti
View attachment 785972
13900KS P+HT + 5090
View attachment 785973
9800x3D @5550MHz SMT Off (8c) + 5090 (me)
View attachment 785974
The man in the video has a score lower than 4070 ti (only because CS2 is on low settings), and yeah P+E cores only.
But yes, I agree, it all depends on the game
I personally use a copy of Windows Enterprise iot ltsc and it is also mildly de-bloated. I'm running 6400 c32 ram which probably is close enough to 8000 with higher latency. In the grand scheme of it all even though there are some Fanboys I think a lot of them have settled down to the point where I even personally ran a 9800 x3d and I still run my 13900 KS and I've come to realize that 1% lows do matter a lot I'll go as far as to say that they're the most important thing for me the smoothness of the gameplay means everything for my experience. Simply put I don't care which CPU is faster or slower all I care is that the CPU that I'm using gives me a very good playing experience and this video for example shows that the 14900k still gives you a basically flawless game playing experience whether he's tuned it very aggressively to even being tuned mildly I still feel like it's the same and close enough either way.
