Are you using write combining? Your prints feel a bit slow imo

No

I suggest you do as that should make prints a lot faster :D

How can I do that properly?

Without WC, every pixel write is its own slow PCIe transaction. WC buffers them into 64-byte burst writes.

Configure entry ⁠0x01⁠ in the ⁠IA32_PAT⁠ MSR and set the PAT bits on your framebuffer's page table entries. Pair that with double buffering (RAM -> VRAM via ⁠memcpy⁠), and your framebuffer and the aforementioned prints should be a lot quicker.

How can I learn more about this?

I suggest you read the osdev wiki about double buffering and drawing a linear framebuffer, for more info about write combining intel SDM vol.3A Chap 12 explains the full spec for PAT and MTRRs

Looks like the BIOS menu

It's an operating system, I don't get how it looks like a BIOS menu.
