In conjuction with these dll's,

Without these dll's you will get jaggies on the coastlines with landgeometry=3 (which i use), however, if you use landgeometry=2 with these dll's, you will get jaggies on the coastlines , so be careful.
these dll's were part of a pack of 5 that 1C release as beta 4.09 dll's.
There was some other stuff that i suggested to jabo, but that was all mod stuff.
Its quite possible that this setup can be improved on, there may well be settings in my openGL that can be improved, some of them i have no clue what they do, but this is all info i have gleaned from other forums.
anyway, there you go
