Quaz51 认为爆炸效果PS3版本更好：
interesting explosion comparaison, seem really better on PS3. i'm surprised
apparently the TV quality in the game is also better in the PS3 version (Bluray capacity probably)

FP10 = 10 bits for RGB components, and 2 bits for alpha = 32 bits per pixel

FP16 = 16 bits for each component = 64 bits per pixel

能把那些对比视频看出XO版本好的才是“本事”，有个对比，在海边旋转视角，XO版本那FPS数值低得可怕，还有DRAW-IN和LOADING时间对比，XO一败涂地，光影也不如，抗锯齿也不如，唯一安慰的就是清晰度了。

Past GTA titles have had mild-to-serious framerate issues and technical glitches, because the games were trying to do far more than the PlayStation 2 could handle. While GTA IV is pushing the PS3 and 360 to the limit, it also runs amazingly well. Sure, there are framerate hitches here and there and (particularly on 360) there is some texture pop-in, but it actually runs better than I expected. That a game with great AI, an awesome physics engine and a detailed open world runs so well and with such short load times is a technical marvel. For that, I can forgive framerate issues and some noticeable aliasing.

The art team gets major kudos for creating a living world. There is great texture work in the environments, a nice field-of-vision blur of buildings in the distance, some excellently modeled cars, ball-jarring explosions, phenomenal water effects and one interesting-looking Eastern Euro for a lead character. Sure, it's not a game that runs perfectly all the time, but the technical elements almost never get in the way of the gameplay.

For those wanting to know which version looks better, the edge goes to the PS3. The textures and framerate are comparable, but the PS3 has far less pop-in. The 360 has richer colors, but the PS3 has better anti-aliasing making it look a little cleaner. Because GTA IV can preload onto the PS3 hard drive, the in-game loads are faster. Don't worry Xbox owners, the load times are rarely more than 30 seconds and don't occur very often. The slight visual edge goes to PS3, but the 360 is no slouch. Either version will do you proud.

None of these little flaws take away from Liberty City's breathtaking vistas, incredibly varied scenery, and lived-in look (the PS3 version has the slightest visual edge, plus motion-control support -- but then it's missing Achievements and the eventual downloadable episodes exclusive to the 360 game). The city just feels alive.

While the PS3 and 360 versions of the game are functionally identical, the PS3's visuals sport noticeably smoother edges, along with a warmer color palette that makes everything look slightly more realistic. If you're looking to compare Accomplishments with your Achievement-hoarding friends, though, forget it - GTA IV ignores these half-assed consolation prizes altogether. PS3 owners also have to put up with a nearly eight-minute installation the first time they start the game, which puts the normally slower Blu-ray load times on par with the Xbox 360 version. (That is, unless it's running on a 360 with no hard drive, which we're told will face much longer loads.)

While GT usually puts up head-to-head videos, the official video review is only for the 360 version. They have yet to play the PS3 version.

They do mention a few techical hitches here and there (with framerate), but since they can't compare it to the PS3 version, there's no way of knowing if that's for both versions in this case.

While I don't understand the language, here's what Forsete says it translates to (and if anyone can confirm this, that'd be awesome):

Although it's got a few problems that pop up from time to time, Grand Theft Auto IV is still an absolutely gorgeous game. Like the previous games in the series, it suffers from some texture pop-in and draw distance issues, although these should in no way affect your enjoyment of the game. It's easy to just consider those technical flaws the price you've got to pay for admission to the most impressive game world ever created. There's so much going on that you'll only really notice the flaws if you look for them, and if you're doing that there's a good chance you're missing out on something spectacular. The overall art design and visual aesthetics are extremely pleasing to the eye, and they aren't hurt by the technical issues.

For those who have to decide between the Xbox 360 and PS3 versions, we should mention that these flaws are slightly less noticeable in the PS3 game. There are a few other minor differences as well, the biggest being the PS3 game's Sixaxis controls. You can use the controller's tilt feature to perform wheelies on motorbikes or control your helicopter, but it just ends up feeling forced. You're much better off just turning them off and sticking with the default control scheme. The Xbox 360 version, on the other hand, has Achievements and features a more intuitive controller (though that may just be this reviewer's personal opinion). Both versions are excellent, so you really can't go wrong

几乎清一色说PS3版本要好，看来都收黑钱了，悲歌继续中。

当年你和我辩论RR6与RR7同一幅图时的激情还历历在目呀，RR7的分辨率是高于RR6的，然后对于RR6其它地方怎么比RR7强，你当时是怎么说的？对于GTA4，要不要再从什么HDR、锯齿、特效渲染以及什么远近层次感等方面来谈谈 ...

选择性忽视或接受，太好解释了，可惜出来混迟早要还的。

没有硬盘安装造成的缺陷是事实，想把这个都否认了，真是可笑之极。

看LS的意思，到底是赞同同一个地点同一个时间同角度的对比还是不赞同呢？好欢乐的帖子。

当然是赞同了
有条件的话尽量来同角度对比了
当然质疑的话当然可以自己去探索疑问。然后拿出对比以理服人:D

那就按WYP说的，去找同时间同角度同地点的大楼消失对比视频吧。我还是那句话，想否定硬盘安装带来的优势，是可笑之极的。

先发张图垫垫场。

对比视频：http://www.gamesradar.com/video/v-20080429115433544062

再来对比视频，图像对比中的光影差别，39秒时地面草数量的差别，过场对比中的色彩差别，最后的LOADING对比更值得看。

反ＳＦ是不是要说，因为时间或者天气不同，草的数量不同呢？ＰＳ３的草是新长出来的．
另外ＬＯＡＤＩＮＧ时间不用看天气吧，那差别也早就选择性忽视了．

光源嘛，应景地再贴一次。
FP10 = 10 bits for RGB components, and 2 bits for alpha = 32 bits per pixel
FP16 = 16 bits for each component = 64 bits per pixel

几个网站的对比视频看下来，对分辨率差别倒没有深刻印象，其他方面PS3版本完胜（读盘速度、光影、画面中物体数量、桢数、POP-IN、远景闪烁、爆炸效果），GTA4马上就要到手了，爽！

天师不是在说网站评价帧数完胜吗?

这写论眼无敌了,自己回去看我怎么说的把.
"几个网站的对比视频看下来",这句话没看到?

让没有AA的游戏达到4倍AA的效果，还是降低渲染分辨率然后再插值输出就成，有这么好的方法当初HALO3咋不用呢？
