Ignore the PS4 dev, seems like a pointless comment. More quotes at the source.
PS4 ICE Team programmer Cort Stratton added that, “New SDKs can significantly improve performance on the same hardware, yes. Dunno about DX12/X1 specifically, of course; not my dept.
He also said that people have a right to be skeptical about performance gains. “Good; always be suspicious of ANY perf. improvement claims. e.g. what *exactly* got 50-100% faster? Faster than what? Details!”
Treyarch software engineer Dan Olson had a less amused take. “Here’s an article… no idea why people go on record for stuff like this.”
Programmer Dean Ashton found it downright hilarious. Either that or life-threatening judging by his response. “2x perf on Xbox One when using DX12? That article nearly made me choke on my cup of tea.”
Seems it's not just the fanboys that are skeptical. Discuss.
