SGSSAA looks best, followed by DSR @ 30%, GeDoSaTo 3840x2160 Lanzcos looks pretty bad. Maybe try bicubic, i find it's the middleground between smoothness and sharpness. Lanzcos inherets too much aliasing. (Although I will admit 3840x2160 Lanzcos has the best texture/mipmap detail, look at the distant objects, you can see more defined textures than any other option, however borderlands is the kind of games where you can smudge some of that up for performance, by upsampling, or for looks, by adding AA. Texture detail is far less important) I've noticed that lowering the resolution not only boosts my fps, but how much physx degrades performance. It's buttery smooth once I start getting down into the lower end 2k resolutions (my screen being 2560x1440). Smooth physx performance at ultra (physx level) is actually the most impressive visual thing about the game. It seems a bit excessive that each physx particle is shadowed ingame though. Maybe lowering the shadow resolution would boost the physx fps dramatically, since during gameplay I can have thousands of shadowed particles and rocks all casting 2048/1024 shadows. That's like the entire skyrim's landscape in terms of polygon/shadowing just for physx clutter.
