The performance is overall good but the performance villains is yet the shadows and post processing above high in the Rx480.
With the following settings I can reach about 66fps with good consistency but there are some fps loss when using a zoomed scope either in picture in picture or normal mode(not so big as in pic-in-pic).
In the picture the texture is high but if I put it in Very High there is no harm. Texture streaming pool or AA filter dont seem to have any impact on performance in my system at this time. I just test in Local Play and in Refinery map(where I get the worst performance) in the last minutes. I didnt find any but or anything else to complain.
