You will have to try around to find the right settings. Stuff like texture filtering and anti aliasing mostly depends on the GPU and driver. Sadly SE screwed around with the D3D code and it's almost impossible to override their settings with the nvidia control panel. Same for ATI though. Edge detect AA only seems to work in fullscreen mode for me
Let's just hope they work on the engine some more instead of adding tiny content bits every month that entertain us for a few hours :P
