Futher adding to these; Did you cross tighten the screws to get even pressure?

Hmm okay. Sounds kinda weird how two very different PCs experience the same stutter, with a fully updated and clean Windows... Did you use the same monitor with both PCs? Do you perhabs have access to another monitor you could try? Again, I'm assuming you have set your monitor to its highest refreshrate and so on.

Assuming you install all drivers and update firmwares and BIOS, then what program do you install and have running? I once had HWiNFO running in the background with Rivaturner to show HWiNFO stats in video games. Having HWiNFO running causes a lot of stutters, especially in video games with high framerates.

I'm reading that the 4080 and 4090 FE cards have zero RPM mode, so the 4080S must have it too. If you have the 4080S card and you never see the 0RPM mode in action, it may be caused by having a high refreshrate monitor. When I'm using my 120Hz monitors, my GPU idles down and goes into 0RPM mode but when using my 240Hz it does not.

I've experienced the exact same, when using my 5120x1440@240Hz (primary display) and 3840x2160@165Hz(secondary display) monitors. The cause was Multi-Plane Overlay (MPO), a power saving feature that is enabled by default on a Windows level. If you wanna give it a try, you can disable it via a regedit: Go to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm", create DWORD called "OverlayTestMode" and give it value "00000005" - restart your system. (Windows update can revert this DWORD change I've read but never seen Update revert it on my system).

Use an overkill PSU, just like I do, with 0RPM fan mode until a certain degree or load is hit. I have never heard my HX1200i spin up during gaming, always dead silent

Alright, sorry to hear that.

That is just factually incorrect. Like seriously, are you trolling?

I guess I would try and update the BIOS if any newer versions are available.

So true... I remember the first time I enabled HDR with my OLED tv. I thought it did not enable because it still looked so "good" and normal in Windows. That day I learned how shitty almost all PC HDR monitors are

Not saying what you're saying here is incorrect, I'm just adding to it; Sure, I have seen bugs with HDR here and there (obviously). In my experience, when colors and/or contrast is blown out, that is because whatever game or video you're playing is rendering in HDR mode but your monitor somehow bugged out and are actually displaying in SDR mode. Displaying video or games in active HDR mode on a display in SDR mode with exactly do that, blow everything out like crazy, because so much of the spectrum is missing for displaying the HDR correctly (because the monitor actually is running in SDR). To fix this, simply disable and enable HDR again in Windows.

I have used HDR a lot in Windows 11, and on 5 different monitors and with 2 different PCs - all worked perfectly as intended. Never had to restart or do any weird shenanigans to make HDR work. I have used HDR on: Samsung Odyssey CRG9 Samsung Odyssey G9 Samsung Odyssey Neo G7 Samsung Odyssey Neo G9 G95NC LG CX (OLED TV) How I use HDR: First I turn on HDR in Windows settings (to put the monitor into HDR mode). Then I download the HDR Calibration tool from Microsoft Store and use it to create a profile for all my monitors. Then, with HDR enabled in Windows, I simply start whatever game I wanna play. Then the first time I boot my game in HDR, I usually just have to go into the games settings and enable HDR. And there we go, simple as that, works everytime. If doing the same does not work, I would suspect the monitor you're using to have an old buggy / unstable firmware. I know Samsung loves pumping out fixes for their monitors long time after release. I see you have a G5 as well; try firmware update it.

This thread crashed hard, damn

Actually, I've experienced that too but I don't have ANC.
