It also had to do with Silicon Studio releasing the Press Release not S397, as Marcel said on Discord earlier: Marrs-Today at 17:44 Just to answer an earlier question. This is an announcement by Silicon Studio about us using YEBIS so the timing is all theirs. I'm sure most of you have recognized the track, Toban, which does look really nice in DX11.
It's not really any news, it was already revealed during DX11 release announcement that rF2 is using Yebis for post effects, so no point in S397 making a special news item about this.
