dede11,
Welcome to Gentoo.
Your kernel command line bothers me | dmesg: | | kernel-6-6-74-gentoo.img root=/dev/mapper/vg0-root ro rd.driver.pre=vfio-pci rd.luks.uuid=c32b911d-4824-4e81-b7de-c6195bb56303 rd.luks rd.lvm rd.lvm.vg=vg0 rootfstype=ext4 nvidia_drm.fbdev=0 root=/dev/mapper/vg0-root amd_iommu=on iommu=pt amdgpu.dc=0 |
From modinfo amdgpu
| Code: | ...
dc:Display Core driver (1 = enable, 0 = disable, -1 = auto (default)) (int)
... |
That means amdgpu.dc=0 turns off the amdgpu driver.
Take the amdgpu.dc=0 away from the kernel command line.

dede11,
| Code: | | [ 93.131520] amdgpu 0000:14:00.0: [drm] Cannot find any crtc or size |
The crtc is the Cathode Ray Tube Controller. It was named a long time ago. That's the bit of the GPU that drives the display.
Is unlikely to be a CRT today.
Sizes are usually provided bi the EDID data that is read from the display.
Pastebin all of dmesg please.
What display (make and model) is connected?
How is it connected?
== edit ==
Your 6.6 kernel predates your hardware but your IGPU has been around for a few years.
It won't do any harm to try the 6.12 kernel, which is the new stable.
== edit some more ==
| Code: | | CONFIG_VIDEO_NOMODESET=y |
should be off. AMDGPU is a modesetting driver.
If you need to force that option for debug, there is a kernel command line option. From memory, nomodeset. It's only for debug as it prevents all the modestting drivers from working.

The big time difference worries me

Also there is nvdia mentioned

Is this a case of https://packages.gentoo.org/packages/sys-power/switcheroo-control , since you have the CPU and external one?
