4 days ago i updated my GPU ( GTX 1070ti) into the latest drivers , since then i am expiriencing mass fps drops when i load 3x Copies of D2R , this was not an issue right before the GPU drivers update all ran perfectly !

I tried to roll back the rivers but the problem still remained !

Today i decided to look closely the task manager and what is actually happening when 3x D2R are loaded , i noticed in the GPU engine tab it says gpu-0 copy in all of the 3 D2R instances!

I googled gpu-0 copy and i have seen that this is actually some sort of a problem which happene dto other players on different games aswell!

As far as i understood it is supposed to say GPU 0 -3D or ?

Any thoughts on how can i fix that problem , been struggling wiht it for days!

Sounds like you're running partitions on your gpu? You'd need to reset the partition tables not roll back drivers to fix that

i am not good in hardware and i do not exactly understand what i did wrong and how to fix !? Could u please explain it simpler !

I absolutely did nothing unsusuall , i just updated the GPU drivers 4 days ago

EDIT: Yes i used to use Hyper-V with option the Hyper-V to use my GPU but since the first time i made that , i did 1-2 GPU updates like the one i did 4 days ago and i did not had issues!
