Yep, head on over to the Calibra page (or scroll down on the right to the .site section) and check out the latest work myself and Jamie have been doing. Almost there ;)
Halo 2. It is teh pwn. My overpriced £306 GeForce 6800GT. It does rock though. Half Life 2 running at 1600x1200 on the above card. Or.. just Half Life 2. 4 teh win! My engine rocks. Despite not being finished. Keep an eye out.
