I just tested how mine ran at 4k on my TV. Not so hot. lol It was like 20 to 25 fps at all ultra settings. Everything at high and foliage at medium it ran locked 30fps.Yeah your colors have really improved. It feels artistically framed too.
My main goal is 1080 at 60fps locked at ultra. It hits that easily so far. I haven't done any LOD optimizations either so that will help.
Looking at those first 2 images, I just want to delete that from my brain. That looks shame compared to my newest one. I honestly thought I would never get to the point I am now. I'm so so so happy with it now.
How much control does Unreal give with optimizing? What's the draw call count?
