approx two years ago i tried to combine my Gaming Rig and mit HTPC in a single machine. Back than the problem was that the drivers for the NVidia 1050TI i used were not really optimized. If i recall it right there was no support for the Video decoding engines at these Nvidia cards, so i abonded that idea quite fast.
Okay two years have passed away now and i want to give it another shot. Because i plan to switch to an AMD GPU in the next couple of months i liked to asked how good the support for NVidia and AMD GPU's is today, also regarding 4K and HDR.
