people over reacted to God Rays being a performance killer
it's Shadow Distance that has much more impact on FPS imo
Fallout 4 is a very strange game engine
I've had instances in Sanctuary where my framerate goes below 40 FPS, but when I go out exploring and eventually return to Sanctuary...
not familiar with AMD GPUs?
it's called PowerTune and it's because if you're playing FO4 with capped 60 FPS, then the AMD GPU down clocks because it's running out of stuff to do due to 60 FPS cap.
here's my R9 290 GPU load when idling in doors in FO4. GPU load goes to 0% a lot.
if you have a freesync monitor
if you really don't like Nvidia
if you strongly believe in AMD DX12
if you strongly believe in AMD continuing to improve driver performance while Nvidia driver improvements will stop once they start focusing on their latest & greatest architecture
otherwise...
possibly better binning resulting in more aggressive / non-aggressive clocks
difference in HSF used
performance difference between 390 & 390X tends to be around 5-10%

correct me if I'm wrong, if RAM speed actually affects performance, shouldn't the slow RAM speed FPS eventually match up with the fast RAM speed FPS if you stay in a static position or is wccftech experiencing a memory leak?

Either Anno 2205 developers made the game with only Maxwell in mind or Nvidia just focused their drivers on Maxwell and may or may not release a driver update to boost Kepler performance in Anno 2205
