Talking about Vulkan on PS4:
“Let’s say I write a game for the Steam Box and the PlayStation 4 supports Vulkan, the Steam Box supports Vulkan. It wouldn’t be that much more work for me to have my game work on the PlayStation 4. Whereas right now if I want to develop the game for the PlayStation 4, I have to learn their special custom API, that has shader languages that are different than what I’m used to, and I’m pretty sure that I have to send stuff in text instead of binary form.”
