I am using it regularly and I've some minor issues of lag. Apart that, I must say that exploring around more some things are weird: you can happen to walk through a tree for instance, or that some bush is exactly over a herb-node, or that there are some additional columns in caves/crypts, that some areas are darker or brighter than they should be. So I'd really like to accept any suggestion from someone who understands a bit more of these things on how selecting/deleting the things which cause funny things. I'd love keep using it since I find it really enhancing in general.
