'Synce' has used CryEngine 3 for a super impressive interior technology demo that uses Crytek's new Global Illumination technology known as SVOTI (Sparse Voxel Octree Total Illumination). The results are amazing, as you can see below.
Synce notes that the demo was created to showcase the capabilities of SVOTI, where he said: "SVOTI means Sparse Voxel Octree Total Illumination. This system can achieve high quality global illumination in real time. In this demo you can change the time of day, and look how the light reacts".
If you want to try out the demo on your system, download it here.
