Man Im getting old, all I could hear in the attached Video was "We made it slower because our modern >$1K GPUs can run it, sucks to be you". "no baked lights, reducing compile time from hours to minutes" Logic error, my brain hurts. If they managed to optimize lighting subsystem to make it run at realtime speed then Light compile time could also take minutes. Why trying to sell it as some kind of speed optimization?
