DirectX 12 games not utilizing GPU

[RS_Cypher]

Hi all

 

I have a strange problem where whenever a game uses DirectX 12 it seemingly doesn't use the GPU. Or at least the GPU load stays between 0 - 5% resulting in single digit FPS.

 

I saw this problem first in Horizon Zero Dawn and tried Red Dead Redemption 2 and Deep Rock Galactic as well. (when choosing the Vulkan API in RDR2 or DX11 in the other games, the problem goes away indicating that DirctX 12 is most likely the culprit).

 

I already tried to do a clean GPU driver install but no luck unfortunately
