This is the problem with physx, its wasted on effects that simply aren't realistic. Same with the wood, its not calculated, its not realistic and its really not interacting with the enviroment, if it was it would be interacting with the bullet and the glass would all be shattering on the side opposite the bullets impact(in general) also the glass is mostly shattering into identically sized little pieces and doesn't seem to actually be taking into account the structure or size of the original piece. IE the bullet hits, the glass shatters, the original piece of glass is gone and the debrie "appears" at the site of the bullet and goes in a premade "explosion" type effect where it spreads out evenly in all directions.
Honestly, thats not even anywhere near close to realistic. Its different, because they put effort into making it different, its not the slightest bit more realistic, and considering its a very very poor effect, and really shouldn't be taking more cpu time, so it feels like more Nvidia pointless inclusion to damage performance and cheat the user out of a better experience rubbish.
Lets be honest, those bits aren't any more interactive, and the "performance cost" of truly accurate physics, is keeping track of many individually sized pieces, and calculating each piece of debries movement individually. The debrie is pre rendered, not moving realistically and therefore can't possible be being heavily calculated each time, especially as each glass shattering effect is all but identical to the last, despite bullets not hitting each piece in the same place or same angle, IE theres no way they should be so similar each time.
Just watched a bit more, its really really awful. THe glass effects don't even centre around the bullets explosion and infact seem to be very slightly "delayed", half the "glass explosion" type effects seem to be in the slightly long location, delayed, and again, the glass will explode evenly in all directions.
THe actual glass panes in the next scene are also "exploding", one bullet hits and a huge area of glass shatters into identical pieces each time, with some going up, and some going forward, and some huge fragments going up, which simply wouldn't be possible.
There isn't a sane person that would defend that as night and day difference, when its actually worse in many bits, and completely unrealistic.
Its different, not more realistic and shouldn't cost ANY more performance, if it does, Nvidia is once again absolutely cheating both Nvidia and AMD users. IE add in a new physics api, make the effects different, but exactly no better, call it realistic, its not, kill performance so it only runs well when hardware accelerated.
Its an abomination on the gaming industry to be honest. Its more realistic debrie than Mafia 1, because its the best part of, what a decade newer, nothing to do with physx, and another attempt for Nvidia to buy off a dev to try to prove how good their physx is. If it was remotely realistic, they'd have a point, unfortunately, the glass wall spherical blowout effect is like something from 5-10 years ago itself. The glass pieces of debrie don't even look like pieces of glass it looks so bad.
