Same performance issues here as OP. My GPU takes 3-4 times longer to draw a frame than my CPU. The 1070 is NOT capable of doing the work correctly (as much as Magnus says it is) unless you start removing all the eye candy. I went from 30 to 15-17 fps in EHAM. I only manage to have 18-22 by disabling all simheaven sceneries and reduce the graphic settings to simple HDR and textures to medium.
A too big burden to have beautiful sunsets.
Let's see in the future, when they tweak the performance a bit. So far, not flyable for me in the A319.
