Any way to turn of filtering on textures?

I think BR don't like to add stuff that 'works on some cards, doesn't on others', i.e, they play it safe and that's why BB is as bug free as it is.

Drake: you can turn off filtering for any texture via the SDK.

First off, sorry for the big piccy :)

Lowering the mipmap lod bias a bit improves the look of an image, adjusting the setting skid mentioned changes blending between mipmaps, and toggles filtering on/off.
