Man, talk about diminishing returns... I mean, I'm a total graphics whore and I'm really geeky when it comes to this kinda stuff, love reading up about it and always used to follow the demo scene etc... But even though I do see and understand that there's so much new and advanced tech in these demos, it just doesn't end up impressing much more than say Battlefield 4 or even 'standard' UE3 games that don't do anything super crazy like Hawken.
We've really entered an era where it's so much more about art than before, similar to how the first Toy Story movie was a technical marvel but by the time we were at Finding Nemo, technical advancements had become so much more unnoticeable compared to artistic distinction.
Either way still cool shit and I still love this kind of stuff, especially when it comes to advances in lighting, global illumination and new AA methods being applied and such.
