Hi,
Suprised this hasn't been mentioned yet. Oh well.
An optimised version of the Cube Engine is now available here:
http://prdownloads.sourceforge.net/c...d.zip?download
You'll need the original Cube files:
http://prdownloads.sourceforge.net/c...s.zip?download
And replace the original .exe with the optimised version.
For those who haven't seen it, Cube is a 3D engine that gives a very Quake-like experience (from a technical, rather than gameplay angle).
It's only compatible with the X50v. This version is well worth checking out. In my opinion it's actually properly playable now and there are some very good maps available.
Enjoy,
Mark.
