It's been a while since I looked into Deus Ex mods. I should probably do this at some point since it has been a while since I played the game.
In any event, I've used this link to keep up with some mods that have been in production for quite a while.
There are a few total conversions that have been completed as well as an OpenGL renderer that is worth looking into. The mod "Shifter" seems like something to look into as well.
