Gigarays.. It just works. :P
I wonder if the continuous deep learning neural network training for every game and every resolution is sustainable for NV to do.
I don't think so, no. Maybe, if they continue to price their upcoming cards like as of late, it might be or should be sustainable. Training their AI to be better at training itself will still cost additional resources. I feel like DLSS will have the same fate as SLI. Some games supported here and there, but will mostly cause some level of headache/s for most. But I'm still hopeful (mostly) since this is a brand new tech, and I want my 2080 to live longer than my 970. :)
On the other hand though, global illumination ray tracing, even as primitive as what we have today, is what I'm really most excited about. It's probably the most taxing of them all but it should provide next level realism. And I've read somewhere that it can reduce development time by putting just a few light sources and let the light bounce off objects naturally. It's most likely not that simple, though. But those reflection shit in BFV does nothing but annoy me. It's like the just did it because they can and they want to.
