PrayForDeath: It's a matter of personal preference. I would choose UB over SSAO because I absolutely hate jaggies and love how the game looks with UB on (did you see Zoltan's beard without UB? it's HORRIFIC lol!)
Same here... I hate jaggies :P
I've tried a lot of things with NVIDIA inspector, NVIDIA control panel but I can't increase AA quality of the game, because I love the smoothness without US off... always 60 fps but I would like to increase at least a little the quality of the AA. I hate when moving the camera and a lot of things in the screen flicker, it distract me a lot.
Another thing that I hate is when I'm moving the camera and the shadow of the grass flickers when SSAO is enabled, Have you seen it? It's terrible!!
If someone tells me that there are a solution that can reduce to 0 that flicker and jaggies effects but at cost of reduce the quality of the textures... in my case I will choose the first.
