Darkvision and Ultravision override

[Void]

I'd like to know if there are any overrides that improve effect of Darkvision and Ultravision.

Basically, after switch to EE, the effect of dark vision and ultravision became incredibly subtle, and it is currently a very light source above the character that barely lights up anything. The light is pale blue for darkvision, and purple for ultravision. What's worse, both effects turn off when character comes "close" to a light source. Where "close" is something like 25 meters.

As a result, even with those abilities, there are places where you can't see a thing.

Is there an override that improves the effects? In original neverwinter nights ultravision used to brightly lit pretty much everything, and darkvision used to work much better as well.
