Those pics really are incredible. Photorealistic. I'm close to that level but not quite with the smoothness and richness of yours. Would you mind saying what video card and processor you're using, and also the main texture mod you're using (if any)?
I'm on a PhenomII X6 1100T with a GTX460 and using the Lite version of the 2K Mod from SkyrimNexus plus a bunch of individual mods that fill out the trees, increase building material quality, ice, water, etc. But I'm wondering if the difference between ours and mine is that you are using the full 2K mod. I started out with that, but I took an fps hit that was pretty bad.
I'm also running the FXAA post injector mod with another lighting mod that goes hand in hand with it, with a preset which adds a lot of clarity and more rich colors plus bloom management. Just wondering if that sounds anything like what you're running.
