You Owe me 80p!
One item making the interwebs rounds this week was the scandalous revelation that Halo 3 runs at “640p” which isn’t even technically a resolution. However, the interweb detectives did notice that Halo 3’s vertical resolution, when captured from a frame buffer, is indeed 640 pixels. So what gives? Did we short change you 80 pixels?
Naturally it’s more complicated than that. In fact, you could argue we gave you 1280 pixels of vertical resolution, since Halo 3 uses not one, but two frame buffers – both of which render at 1152x640 pixels. The reason we chose this slightly unorthodox resolution and this very complex use of two buffers is simple enough to see – lighting. We wanted to preserve as much dynamic range as possible – so we use one for the high dynamic range and one for the low dynamic range values. Both are combined to create the finished on screen image.
This ability to display a full range of HDR, combined with our advanced lighting, material and postprocessing engine, gives our scenes, large and small, a compelling, convincing and ultimately “real” feeling, and at a steady and smooth frame rate, which in the end was far more important to us than the ability to display a few extra pixels. Making this decision simpler still is the fact that the 360 scales the
“almost-720p” image effortlessly all the way up to 1080p if you so desire.
In fact, if you do a comparison shot between the native 1152x640 image and the scaled 1280x720, it’s practically impossible to discern the difference. We would ignore it entirely were it not for the internet’s propensity for drama where none exists. In fact the reason we haven’t mentioned this before in weekly updates, is the simple fact that it would have distracted conversation away from more important aspects of the game, and given tinfoil hats some new gristle to chew on as they catalogued their toenail clippings.
1080p at 60 fps is awesome for fighting games and barely a stretch for Live Arcade games. But if you want epic battles, dozens of bad guys, huge vistas and colossal structures, with advanced AI, HDR lighting and explosive physics, then you’re not getting those at 1080p at 60fps. Actually, that’s not entirely accurate – Halo 3 will display at 1080p through the Xbox Elite with its scaler and HDMI port, but not natively. We’ve seen it do just that and it looks utterly lovely. So if you have a 1080p TV, enjoy it yourself in a few weeks. Most people, and I mean the VAST majority of people don’t have a 1080p TV, so it would be foolish to sacrifice even a single feature for a bullet point number on the back of a box.
UPDATE: It has been pointed out to me that all 360s, even the "vanilla" Core 360 will display games at 1080p over component, if your TV accepts a 1080p signal over component. We were simply describing the setup we use in our test lab. You don't need an Elite for 1080p, just cables and a compatible TV. There are some 1080p capable TVs that won't accept 1080p over component, however.

真不要脸,做出连原生720p都不到的次世代游戏,说话还那么理直气壮,MS不是有规定游戏必须达到720p+2AA吗?看来也是废纸一张。

我觉得应该是对机能的妥协,使用两个FRAME BUFFER来达到效果但是节省机能,不知道技术细节是怎样的

之前那些不愿意承认的软饭是垂死挣扎啊
因为他们不愿意承认640垂直是原生分辨率啊
谁知道bungie会出来说dual frame buffer呢

用两个RT来做HDR。HL2 LC就用过。
至于Halo3 HDR的技术细节,MS有发表过。
1152x640的分辨率可以保证2 32bit MRT+不用tiling。

我记得去年天师说同一游戏PS3版本和Xo版本画面相同的话就说明PS3的性能是XO的2.25倍,因为PS3的游戏都是1080P的,(1080/720)的平方就是2.25(大意,差不多是这么个算法)
另外天师也发过帖子,说PS3可以 ...

做bungie fan真幸福
官方出来帮玩家可能在网络上受到的攻击先买单了 :D
真同情那些挺了某个游戏结果被厂商的行为倒打一把的玩家啊

机能所限,就算你加入了全程的HDR,也改变不了你是个低清游戏!你比WII的游戏强不了多少!而且XO上面只会出FPS、SPT、RAC,根本没有RPG!

2个Framebuffer = 1152x1280的分辨率?
OMG, 这种话都有人说得出口。扫一下盲: 不管多少个RT都不提升分辨率。
游戏性就游戏性了, 卖得也那么好, 赚钱又那么多, 技术上还是不要捣浆糊了。不能学老任么?闷声 ...

所以他們用AA 以及 解析度拿來換光效了
這種作法其實有利有弊
有一些螢幕會把沒AA這一點放大得很嚴重、造成一個滿是鋸齒、很糟的 ...

鲜明的几近无赖的表态 换一个角度提出热点问题 让sf回击可以不要集中在画面上
版主这种舍身成仁的精神 要是要膜拜的
有版主这等人才领军rf
怎能不叫 宵小得志

说点自己的看法
这次halo3的画面原生640p 个人感觉有点xxx门的味道
未经后的大战留下了不利因素
lu的看法不会因为我们这些cu战翻天就会有真的有 哦 原来标榜性能的主机其实也可以只要关注游戏性的看法 ...

原来Bungie从来没说过native 1080P,甚至没提过720P
果然没吹牛,这下某群体该怎么喷啊
软饭有了bungie,头上顶着青天了
原帖由 doomking 于 2007-9-29 12:52 发表
画面-----销量-----游戏性
真1080P(回放绝对没加强画面!)------回放加了AA仍然是1080P!------插值到1080P也算------官方从来没说过native 1080P!
集体转职了么
以后 ...

大汗,连版主都急了,口不则言了,可见这件事情打击非小。
其实1080p是软饭自己拿出来说事,而S饭就一直质疑,战区的帖子还历历在目。
到现在还有软饭在自己的签名里炫耀这事,这能怪谁?
