crash with laptop auto switchable graphic cards

Hi, here's my setup: Sniper Elite 3, Reshade 3, Windows 10 x64, laptop Dell Precision with dual graphic cards automatically switchable (Intel and nVidia).
To make Reshade work with this game I have to deactivate either one of the graphic cards. I deactivate nVidia in windows Device Manager or the onboard Intel chip in the BIOS. If I leave both activated (auto switchable to save energy) then Reshade will crash at launch ! Could a coder look into that or is there any easy fix ? Thanks
