Thought this might be of interest, if you haven't seen it yet. I was surfing the forum earlier today and came across a pretty cool thread by GameCore user @LutinMalefique - he has been doing some experimentation with the famous 'Sponza Atrium' 3d model that has been used by a number of companies to showcase rendering technology and lighting.
He has posted a number of very cool screenshots and a downloadable demo of the Sponza scene - both of which are very cool demonstrations of GameCore's rendering capabilities.
