I can't see anything in that video that absolutely
could not be done today. Which I suppose is fairly obvious, as CryTek were showing it yesterday - and unless they have a time machine (
they are a clever bunch though... ) it has to be possible today...
Yes, unless (which is possible) they have access to some seriously hot hardware that I've not seen. I'd make that assertion based as much on the draw-depths... that level of detail/effects, that resolution, that draw depth - all looks a bit much for current hardware.
Then again, that's not to say there's anything "fake" about it. It's quite possible it's DX10 level technology - just running via the REFRAST until the hardware is available
Just my thoughts though, any information I might have access to I'd probably get shot for mentioning in public...
