I think I should add details. in 1440p works perfectly for me, but as I said I am aiming at the goal of 4K @ 60fps (I do not really like to try to play at 30fps). Without ENB works (4K @ 60fps using my rig), but with ENB the framerate drops to around 30~40fps. And funny enough, that with or without heavy effects activated like SSAO, somewhere in the ENB code there is a large loss of performance when you increase the resolution to 4K.
