I’ve read a lot of opinions that share yours. I’m certainly not a systems engineer, and I respect your knowledge and experience. One of the main points made is that Windows 11 is well optimized for modern multi-core CPU’s. In short, just let it 'Do its thing."
I also know that I should probably do some comparative tests, running the test software I own, like CapFrameX, Aida64, Blender, and CineBench, disabling the following ‘tweaks’ one-by-one, and seeing what difference it makes in the sim.
Process Lasso (enabled)
ISLC (enabled, with HPET disabled)
nVidia Profile Editor (MSFS tweaks)
Rbar (currently enabled)
Virtualization (currently disabled)
Hyper-Threading (currently enabled)
Rolling Cache (enabled on a RAMdrive.)
As a scientist, you know that objective testing, not ‘feelings,’ are the way.
But doing so takes a lot of time, and I ‘feel’ like my system (5800X3D, 3090 Ti, DDR4-3600/CL14) is performing above its weight class.
Maybe I’ll appeal to the empiricist in me, and do some more testing when I have some time. I’ve used Aida64 to determine that tweaking manual memory timings in BIOS was a fool’s errand. ‘Auto’ proved to be the best option. Same with trying to OC my GPU. Any gains in performance were accompanied by standing too close to the edge of instability. Not worth it.
Perhaps the same can be said of Process Lasso. Only testing can prove that. Thing is, as you know, a computer is an amalgam of synergistic hardware and software. You can’t say “This is good, this is bad” without multi-variate tests.
