~! Ultimate GTAIV Performance Fix !~

　　The Idea:

　　You've heard this rant a million times, GTAIV was future proofed all reflections and shadows are scaled with the resolution. A stupid yet seemingly unfix-able problem that makes the game a mess. Playing a game in 1024x768 or lower is not acceptable. If I wanted to do that I would pull out my P2/P3 with its 32/64mb graphic card. From looking at GTAIV, it has a lot of new technology but nothing that should struggle to run on 8800's or even 8600's. Its that resolution scaling, im sure of it!.

　　想法：

　　你已經(jīng)無數(shù)次聽到這樣的言論，GTAIV已經(jīng)被進(jìn)一步證明 所有的反射和陰影都與分辨率的大小有關(guān)。(國(guó)內(nèi)的結(jié)論是和富裕的顯存數(shù)有關(guān) 值得商榷)這個(gè)看似無解的傻逼問題把這個(gè)游戲變成了一坨屎。用1024x768或者更低的分辨率玩這游戲讓人無法接受。如果我真的想這么做的話，那我只有把我的32/64 Mb顯存的P2/P3拿出來了。(。。這東西還留著 老外很變態(tài))仔細(xì)看看這個(gè)GTAIV，雖然有很多新技術(shù)，但也不至于讓8800系列甚至是8600系列跑的如此艱難。(老外把ATI無視了) 我很確定是分辨率縮放搞得鬼。

　　更新一點(diǎn)說明 根據(jù)官方README 光影質(zhì)量確實(shí)只和分辨率有關(guān) 這就是為什么游戲本身的限制顯存不夠不能開高分辨率的一個(gè)原因

　　QUOTE:

　　根據(jù)R*官方Readme上面的原話 光影質(zhì)量確實(shí)和分辨率有關(guān)

　　Video Mode

　　Resolution scaling effects water, reflections, shadows, mirrors and the visible viewable distance. The resolution settings relate to the amount of available video memory. At 2560*1600 the game will require 320MB of video memory in addition to all the memory required for content. At 800*600 the game will require 32MB of video memory in addition to the content. Medium resolution settings are recommended for most users as higher settings are only usable if there is available video memory.

　　可以看出 2560*1600分辨率下的光影需要320M的顯存 而800*600分辨率下的光影僅需要32M顯存

　　看來國(guó)內(nèi)說和剩余顯存數(shù)有關(guān)的方法是沒有根據(jù)的

　　The Plan:

　　There must be a way to correct this mess. Lets look at our checklist.

　　- Configs/Settings Profiles in game directory? /fail.

　　- Will R*'s patch will add more options in? /fail.

　　Not long ago I figured out you can run in windowed mode in 800x600 and then stretch the window larger and it gets around R*'s quality scaling hat would increase the reflection maps.etc that would lag the game and make objects/textures disappear and horrid pop-ins. It made the game look good because you weren't dealing with such a low resolution and the game played extremely well.

　　I wanted to look into this and see if you can achieve the same thing without stretched the window manually every time.

　　計(jì)劃：

　　肯定應(yīng)該有一種方法把這個(gè)問題修正，看看我們的清單(指試過的方法)

　　-直接在游戲里面進(jìn)行設(shè)置/失敗

　　-等R*的補(bǔ)丁在游戲里面加入更多的選項(xiàng)/失敗(這幾乎是不可能的)

　　不久之前 我發(fā)現(xiàn)可以用窗口模式以800x600的分辨率運(yùn)行游戲，然后再把窗口拉伸，這樣能避開R*的quality scaling(指根據(jù)分辨率大小按比例縮放反射和陰影等的質(zhì)量)，這東西(指quality scaling)會(huì)提高反射貼圖質(zhì)量等等，使得游戲變卡，貼圖和模型透明以及各種各樣令人惡心的彈出錯(cuò)誤提示框。這樣做(指以低分辨率窗口模式運(yùn)行然后再拉伸窗口)使游戲看起來很不錯(cuò)，因?yàn)橐环矫婺悴挥妹鎸?duì)如此低的反辨率(指800x600)，另一方面 游戲運(yùn)行的非常好。

　　于是我開始研究是否讓人不用每次都手動(dòng)拉伸窗口而獲得同樣的效果

　　The Support:

　　After browsing the net, I noticed others used commandline.txt to set the size of their window, and some people have achieved resolutions over their memory limit without using -norestrictions and only using the resolution from the command lines. This instantly helped me find the answer I wanted.

　　支持：

　　通過瀏覽網(wǎng)頁(yè)，我注意到一些人通過commandline.txt這個(gè)文件來設(shè)置他們窗口的大小(commandline.txt這東西論壇里面有帖子詳細(xì)介紹了 這里就不說了)，還有一些人不使用-norestrictions命令而突破了顯存限制實(shí)現(xiàn)了更高的分辨率，因?yàn)樗麄兪褂昧薱ommandline.txt 來設(shè)置分辨率。(而不是用游戲內(nèi)置分辨率)這馬上使我找到了問題的答案。
