Back to Dinosaur Island was the first technical demo from Crytek to venture into the world of VR.
In their first short demo you're close to a few dinosaur eggs with the mother roaming around. The demo allows some simple interaction such as head butting the eggs and swatting some flies.
The graphical fidelity is the standard you would expect from Crytek. Just make sure you have a decent graphics card to power this bad boy. The demo is available for the DK2 and works just fine on the 0.8 beta.
