Having some problems with triples. I'm just barely running 4k triples in AC but can't even make it full screen in UI 4k. Keeps defaulting to 1080 and I have to wait as it clicks back to 3840,which takes a few minutes every time it does, even though it is set to 4k in first menu. Will rF2 run 4k? ... I just remembered I'm still using the old UI. Is this the problem?
