Could Not Enumerate Graphics Devices

[Slime In A Box]

1.Under settings go to Device Manager>Display Adapters> right click and disable AMD
Radeon (TM) Graphics

2.Start doom eterna

3.The frame rate will be crappy.. stop the game now that it has started (the game can now
“see” the underlying GPU)

4.Now enable the AMD Radeon Graphics (like how you disabled it in the first place)

5.Start doom eternal again..

The game should run smoothly now (at least it did me).

Hope this helps!

This doesn't work quite right for me and I have to keep the Radeon Graphics driver off while playing.

Try forcing the high performance GPU. In Windows 10/11 go into "Graphics Settings", then under "Graphics Performance Settings" browse for the DOOM Eternal executable ("DOOMEternalx64vk.exe"), and in "Options" choose "High Performance".

Then in the game verify that the high performance GPU is actually being used by enabling full performance metrics ("Settings > Video > Video > Performance Metrics"), they will show you the name of the GPU that is being used.

I used to do the exact same/similar thing, until i found the solution in one of steam threads. Here's what my situation (and fix) was and hoping that's the same case for you.

1. I have a laptop with dedicated GPU 1650Ti and an integrated GPU of AMD with the Ryzen processor.
2. Doom Eternal always used to give me "Could not enumerate physical devices" despite me selecting to start the game with Nvidia gpu and high performance everywhere.
3. I used to start it like this... first disabled amd gpu in device manager, start the game, as soon it starts i enable the amd gpu in device manager, game worked fine like that.
4. Wolfenstein started giving me similar issue for which this workaround didn't work.
5. Went to find solutions and found out maybe it can be amd driver issue that cannot enumerate device properly.
6. OP of that steam thread gave the solution to download AMD Software: Adrenaline Edition , install it and update the amd driver to the latest version and restart pc.
7. Wolfenstein and Doom Eternal both working correctly now without any workaround.

If your situation is the same, try this and let us know if it fixed.

The fix that seekNDstroy suggested worked just fine for me. Such a relief
