I am using the xps 15 9575 (i7-8705G : Vega M GL).
but I can not see the video tab in the Radeon setting.
according to https://community.amd.com/thread/196792, it says that AMD GPU has no display output.
but I think that fluid motion is only computational, even without display output, so it should be possible.
calculation of game is possible.
caculation of fluid motion is impossible.
All driver support for this laptop comes directly from Intel.
Also, Fluid Motion is a feature that is used to generate stutter free VIDEO output, specifically when using PowerDVD.
