Its a free/open source FPS based on the DarkPlaces engine, which is based on the Quake1 engine.
I know that sounds really old, but the game has a ton of enhancements, like motion blur, etc.
In short, it does actually look really nice and is highly scalable. And its free.
Check it out, maybe we could get a DITL server going?
