Using the Fury X we see that DX12 allows for a few more frames per second on average with the Core i7-6700K. However, the minimum frame rate was oddly 19% lower. Moving to the Core i5-6600K we find that again DX12 boosted the average frame rate by a small margin, yet this time we see an even larger 29% decrease when looking at the minimum frame rate.
The situation worsens with the Core i3-6100T processor. DX12 looks amazing here if you focus solely on the average frame rate as it improved the Fury X's performance by 14%. Sadly, we saw a 53% reduction in minimum frame rate and the story is similar for AMD's FX processors.
