Most of the demos are in fact real time, not pre-rendered. However, there is a significant difference between real time rendering that is just zooming in and rotating the view as this dx12 demo, (and pretty much every other real time demo), and in-game interactive rendering.getochkn :I've seen demos like that for probably 10 years on how awesome some new engine or this or that is, but it never really seems to translate down.
Most demos are pre-rendered tough. Doing it in real time and in-engine is quite different and actually impressive TBH.
The biggest thing to take from this is that DX12 will probably allow the same GPU to be more fully utilized in a better way, i.e. it will be able to spit out more polygons which are one of the biggest blocks of more realistic graphics.
ok, lets get this out of the way first.There's no way games could ever, ever look that good and be profitable. That's taking into account that it feels like a fully fleshed out game, labor hours, and still trying to hit the standard price points.... or maybe $120 video games could become the norm. /shrug
Edit: and same dumb AI from 1999 (God I hope not though, not dx12's problem)
