قسمت دوم مصاحبه IGN با مارک سرنی ( LrUsIu5ZcMs )

احتمالاً مصاحبه جدید بوده چون خیلی وقت پیش خودم توی همین ترد خبرش رو گذاشتم که سرنی گفته بود پورت بازیهای PC به PS4 فقط چند هفته طول میکشه نه چند ماه :دی.
حرفش هم درعمل ثابت شده Octodad نسخه قابل بازی ps4 ش 4 هفته اماده شد و Warframe هم توی 6 هفته :دی.
 
خلاقیت در ساخت کنسول بازی یعنی که یه عده مهندس خلاق که خودشون بازیسازا های بزرگی بودن بیان کنسول بسازند
سپاس فراوان سونی
سپاس فراوان ثرنی
دوستان نویسنده بتل استار گالک تیکا تو کا میکان گفته دوساله داره نویسندگی عنوان جدیدی برا سانتا مانیکا گیمز میکنه
 
How The Crew was ported to Playstation 4
تو این مقاله کلی اطلاعات ریز و درشت هست،یه قسمت هاییش جالبن،تو مقاله اشاره شده که CPU و GPU هرکدوم به صورت جداگونه از 20GB/s و 176GB/s پهنای باند استفاده میکنن و گفته شده که استفاده درست و تخصیص دادن درست دیتا بین این دو تو نتیجه نهایی خیلی موثره.

based on our information the GPU has full access to the 176GB/s bandwidth of the PS4's GDDR5 via Garlic, while the Onion gets by with a significantly lower amount, somewhere in the 20GB/s region.Whatever the precise figure is for the more constrained CPU area, Jenner would only confirm that it's enough

هرکدوم از اینا هم اسم جداگونه ای دارن،onion و garlic bus :

The PS4 operates a system where memory is allocated either to the CPU or GPU, using two separate memory buses
One's called the Onion, one's called the Garlic bus. Onion is mapped through the CPU caches،This allows the CPU to have good access to memory,explains Jenner
Garlic bypasses the CPU caches and has very high bandwidth suitable for graphics programming, which goes straight to the GPU. It's important to think about how you're allocating your memory based on what you're going to put in there

The first performance problem we had was not allocating memory correctly... So the Onion bus is very good for system stuff and can be accessed by the CPU. The Garlic is very good for rendering resources and can get a lot of data into the GPU," Jenner reveals

یه صحبتهایی هم از چیزی به اسم toolchain و یسری middleware کرده:

Sony has made a big deal about the accessibility of the PS4 hardware, and a key element of that would be the quality of the toolchain - the series of programs used to create compiled code. For the PS4 developers, the use of the established Visual Studio environment proves to be a key benefit
One thing that definitely helped getting the game to work was that the engine uses quite a lot of middleware. Middleware supporters have been very active on PS4, so there are versions of all the middleware we wanted available

این قسمتش هم درمورد gpu کنسول جالبه:

The PS4's GPU is very programmable. There's a lot of power in there that we're just not using yet. So what we want to do are some PS4-specific things for our rendering but within reason - it's a cross-platform game so we can't do too much that's PS4-specific

آخرین ویرایش:
Reflections سازنده the Crew از پورت بازی به PS4 گفته:
, the Ubisoft Reflections team is now ramping up its staff in order to complete the PS4 game ready for the Q1 2014 release, but the core engineering effort in moving The Crew across to PlayStation 4 was accomplished in six months with a team of just two to three people working on it. Overall, Reflections felt that the process of porting over the PC codebase was fairly simple and straightforward.
