3090FE low GPU usage?

Cool. You'll gain quite a bit of performance with XMP on, as 2133Mhz with bad timings will severely limit the 11900k. Tested BFV since setting XMP?
Your motherboard BIOS is very old, from January. The latest BIOS has fixes, performance improvements and new microcode for Rocket Lake, which will further improve things.

Link above is to the WIFI edition of the motherboard - not sure if you have this or the non wifi one. Either way, update to Version 0707 ASAP, and turn back on XMP!
Be noted, these BIOS updates that contain CPU microcode updates seem quite scary when updating - they'll reboot you PC several times, you'll get quite a few black screens while it loads the microcode updater. Let it run until you're back at POST (my Maximus XIII board took around 4 minutes!)
I got a blue BSOD after enabling XMP so I'm just this minute updating the BIOS to 707!!
Well that's weird:
Updated BIOS
Enabled XMP
BFV crashed to desktop
So I tried it again and the whole PC froze then crashed into a reboot and BSOD, it then tried to boot back into Windows but had another BSOD then just powered itself off?!
It will only boot into Windows with XMP disabled now.
Still have the same weirdness with BFV, GPU usage fluctuates between 70-98%, CPU usage is fairly stable at 60-75%. 150 ish FPS so not near BVFs 200fps cap.

Switched back to DX11 in BFV and it's pretty much the same story except my GPU usage is just 50-60% now and CPU usage is 40-50% with an FPS of just 110??!!!!. I'm not overly bothered about the actual performance with BFV, because it's certainly playable, just wanted to get to the bottom of this new weirdness because I'm pretty sure something isn't right.
Increasing Res scale to 150% just lowers FPS to 70 and ups GPU usage to 70%

I will get you that info shortly, thanks.
Tried leaving all RAM settings to Auto and just settling frequency to 3200MHz and it played BFV for 5 minutes then froze and crashed again. Weird because these same sticks of RAM ran fine with XMP at 3200Mhz on my last Asus board.
Seems to be fine as long as XMP is disabled.

If it's not stable XMP that's worrying, what RAM do you have? Dominator Platinum as per your sig?
Are you running the memory in gear1 or gear2? Gear1 means IMC (cpu's memory controller) is running the same speed as the RAM. You can confirm this in CPUZ by checking "mem controller freq" and "DRAM frequency". 3200Mhz is quite slow memory so you should be running it in gear 1.
In my brief experience of BFV DX12 I found that it stutters a lot the first time I enter new areas on the map which I presume is due to building some of sort of shader cache like many other DX12/Vulkan games do beforehand. Then once the whole map is 'cached' it seems to run without stutters?
In DX11 it's much more likely to run into a single thread CPU bottleneck holding back the GPU.

The reality is that if the resolution is high enough then even if you used the slowest ddr4 memory on the market the gpu would still be at 100% load
Best I can do with my monitor is 3440x1440 and up the Res scale in game to 200%, all that did though was lower FPS to around 40fps, GPU usage went up a bit.
Yes it is a bit worryingly tbh, I'll check that out and get back to you shortly. And yeah its the ram Listed in my sig.
You should start testing one stick of RAM at a time as well. XMP 3200 should be no problem. Might have a bad stick/other memory related issue that BFV is triggering (and the issue when XMP is enabled could point to that as well).
What SA voltage and CPU IO 2 voltage is the BIOS setting by default when you enable XMP? They might be called something else like VCCSA and VCCIO2 in your board's BIOS.
Also, if running CPU at stock, try disabling SpeedStep and enabling SpeedShift (in BIOS). For starters you should see a slight improvement in Cinebench R20, and I think it should help with gaming even though the issue must be something else. If you're running Windows High Performance then it won't make a difference, or shouldn't, as that will/should ignore the BIOS SpeedShift setting.

Looking at this at idle it owuld appear that both frequencies are the same (XMP off obviously).
