Ultra settings with some .ini tweaks. Increased foliage distance, grass density, and some other minor tweaks.
I'm not using a SweetFX preset yet cause I don't really like any of them yet. I've tried some out but they're mostly horribly over-sharpened, and too grey. If I look at grass in real life, it doesn't look grey.
I'll keep trying though until I've found a decent one that isn't over sharpened and doesn't have so much bloom that looks like a nuclear bomb just went off.
