The runtime version ran alright on my PC (16GB ram and 970GTX). To with “black screens” you need to give the thing time for the shaders to compile. It took a minute or two to get going on my screen the first time. Remember this was a cinematic targeted demo for 30Hz on a Titan. It’s not a game, nor meant to show what is expected for mainstream games graphically or performance wise.
Anyone know how to trigger the cinematic in the runtime version? It is in UAV mode. Also Esc, q, etc don’t seem to quit the game! (Edit: NM post while I was typing this answered me!)
