[ Каскадный ] · Стандартный · Линейный 4A Games: У Wii U ужасный процессор, Хорошему танцору...

[Сахар]

Компания 4A Games, разрабатывающая в настоящий момент шутер Metro: Last Light по известной дилогии Д. Глуховского, пожаловалась на процессор Wii U. В компании назвали его "ужасно медленным" и объяснили этим нежелание выпускать Wii U - версию проекта, которая изначально была заявлена. В 4A Games подчеркнули, что не хотят тратить усилия на оптимизацию своей игры под новое "железо", а собираются сосредоточиться на версиях для Xbox 360 и PS3.

Следует отметить, что более именитые компании не высказывали недовольства "железом" Wii U, на которой доступны версии таких кросс-платформенных хитов, как Batman: Arkham City, Mass Effect 3, Call of Duty: Black Ops 2 и других. Неизвестно даже, получали ли в 4А Games последнюю версию девкита консоли.

Speaking as a developer who's worked on the PS3, the Xbox 360 and the WiiU. The CPU on the WiiU has some nice things on it. But its not as powerful as the Xbox360 chip. I think N went to IBM and asked them: 'What's cheap to put on the chip?' and IBM said 'Well we have this sh*t that no-one wants.' and N said 'we'll take it.'. It does have better branch prediction than the PPCs in the PS3 and Xbox360.

The Espresso chip doesn't have any sort of vector processing. It does have paired singles, but that's a pain, a real pain to use. The floating point registers are 64 bit doubles, so when people talk about paired singles I assumed you split the register in two. No the registers are actually 96 bits wide, its actually a double and a single. To load it you have to load in your single, do a merge operation to move that single to the upper 32 bits, and load in your second one. This makes the stacks explode, because to save a floating point register in the callee takes three operations, and 12 bytes no matter what.

While the WiiU has 1 gig of RAM available to the game to use, the RAM is slow. The cache on the chip is also slow. We had tested out memory bandwidth between cache and main memory on the xbox360 and the WiiU. The main memory access on the Xbox360 is about 2x-4x times as fast as accesses the cache on the WiiU. Yes I mean that the external to the chip RAM on the Xbox360 is faster than the cache memory on the WiiU. I don't remember the full results but I think we figured out accessing the hard drive on the Xbox360 was faster than the RAM on the WiiU too.

The optical drive is also slow. I don't know for sure but it feels like the same drive that went into the PS3. And on the PS3 we used the hard drive to cache things to improve load speeds. Without a hard drive on the WiiU we can't do that.

I won't go into the OS, and the programming environment, but let me just say I hate programming for Windows, and I prefer programming on the Xbox360 to the WiiU.

While the GPU in the WiiU is better (probably because ATI doesn't make anything worse these days), they don't have the CPU and RAM to back it up. Who knows maybe things will be better from launch, but I'm glad to leave the WiiU behind.

Sources said graphical quality "won't be a problem" on Nintendo's new console, but a drop in CPU horsepower compared to 360 and PS3 could see Wii U lag behind in areas such as complicated physics and AI.
"Assumptions that Wii U games will look like 'up rezzed' current-gen titles with better textures aren't quite right. They'll look just as good, but not better," one developer told CVG. "You shouldn't expect anything special from a graphics point of view," they added.

A second source working on a big name franchise said GPU and RAM power "won't be a problem" on the new console but, again, claimed Wii U struggles to match PS3 and 360 in processing power.

"We're still working on dev machines but there have definitely been some issues [in porting PS3/360 games]," our source said. "It's not actually a problem getting things up and running because the architecture is pretty conventional, but there are constraints with stuff like physics and AI processing because the hardware isn't quite as capable."

The same source concluded, bluntly: "I suppose you don't need sophisticated physics to make a Mario game."

Просто потрясающе, новое поколение, ага. А теперь вспоминаем E3, ту самую технодемху с зельдой, этот "техно"ролик с карпом, слова Реджи о Каловдутии на ВииЮ через 4 года. Очень некрасиво.

Кроме того, на производительность жаловались разработчики Теккена и Dynasty Warriors.

Ну вспомнил, красивые демки. И что дальше? Мысль разверни.

слова Реджи о Каловдутии на ВииЮ через 4 года.

- а вот это напомни, не вспоминается: что говорил и когда?
