I haven't seen this on here, but sorry if this is old information.
[quote]Anonymous developers have labelled the current state of Xbox One’s graphics drivers “horrible” and claimed the difference between both the Xbox One and PS4 is “significant” and “obvious.”
In a piece about the performance differences between Microsoft and Sony’s new consoles on Edge, a number of unnamed developers have said that while the platform holders continue to refine both systems, Sony’s is currently easier to work with.
According to one source, Microsoft has "been late on their drivers and that has been hurting them.” Another source says that the Xbox One graphics drivers are "horrible".
It is also being reported that the PS4’s memory reads between 40-50% faster than Xbox One, and that the PS4‘s Arithmetic Logic Unit (ALU) is around 50% faster than Xbox One’s.
The article says that a “platform-agnostic development build can run at around 30FPS in 1920×1080 on PS4, but it’ll run at ‘20-something’ FPS in 1600×900 on Xbox One”.[/quote]
[quote]It should also be noted that, for the period following the PS3’s launch, similar accusations were made about that console, with Valve most famously saying it was “too complicated to develop for.”

Wasn't there an "Anonymous Dev" not too long ago that said the Xbox One had a secret super powerful GPU hidden inside itself.
