can't view stuff in framebuffer! /dev/fb0 no such file or directory

I am trying to use fim, w3m and a few other things I tested to view images in the frame buffer (my tty)
I also want to play quake 3 in the framebuffer, among other things.

But I have no /dev/fb0??

I am in video group.
$ groups seeder
audio input video seeder

i also tried it as root in a vm that is a rough clone of my arch install, same issue.

$ uname -a
Linux isoseeder95.home 5.8.12-arch1-1 #1 SMP PREEMPT Sat, 26 Sep 2020 21:42:58 +0000 x86_64 GNU/Linux
using proprietary nvidia driver for gtx 1060
booting via bios (no efi)

unless you have specific reason for using non-uefi. A efi frame buffer support a high resolution tty. how about re-partition and booting with uefi and turnoff CSM on bios.

Hi, my system does not support it.  Or rather, it has never worked on my hardware. I have very buggy eufi firmware.

Are you saying I need EUFI to even display images in fb? That seems a little backwards, linux console could display things to fb before eufi even existed.. was support removed?

I assumed most gtx1060 has a uefi vbios.

I also assumed you passing through gtx1060 to a vm using OVMF. Since [t's suggest by Arch wiki.

I am sorry for misunderstanding, Did you tried DRM kernel mode setting?
