I'm wondering how easy it is for the game developers to incorporate some of these new features.
As you probably know, sadly a lot of games are developed for the console market, with a PC version commonly released at a later date (in some cases years later aka GTA V). Considering Higher frame rates are just starting to be a recognized thing, never mind AI AA, Giga rays etc. Sadly all using AMD graphics. Just don't see consoles getting fancy graphics soon. We will just have to wait and see.
I will probably invents in maybe a potential 3rd gen Vive in a couple of years, before I upgrade from a GTX 1080Ti. However I may need a new GC to run that theoretical piece of hardware. Best get saving now.
