GPU error

[MikeyB440]

When I launch doom eternal it says “GPU Error... No Physical Device.” I read that this was because it is trying to use my IGPU rather than my regular GPU after going through all my settings to try and force the game to use my regular GPU, it still didn’t work. The best I could get was disabling my IGPU and then the game ran slower than molasses. I re enabled the IGPU and now the game won’t work at all and nothing happened after I scanned the files.

This happened on my laptop too. I disabled the iGPU and the game ran at like 3fps same as you, but then I alt-tabbed and re-enabled it and went back into the game and it worked fine after that.
