谁有GTA4的比较好的画质补丁，附有比较好理解的安装教程

去下个ICE12  ，先把GTA4根目录里的D3D9dll文件改为D3D9_1dll 。 然后把ICE12的所有文件解压缩到GTA4的根目录，在去GTA4的根目录找到iceconfigini文件用记事本打开，把里面的东西全删了，把下面的字符复制进去，保存。OK!

//ENBSeries Based configuration file for iCEnhancer
//Does the same thing as ENB
//DO NOT PLAY WITH IT TOO MUCH You might break everything

我的截图，还不错吧？自己改的，纯手打，拒绝复制！！！！

首先，要先使用一个GTA4和RGSC恢复工具。 进去后，点绿色的普通下载即可。。 我的网盘，安全无毒，放心使用。 恢复工具： >请问你的盗版盘装是不是直接点EXE安装，如果是这样的话一般是硬盘版，硬盘版的话错误比较多，大多数不支持升级，所以建议你还是去游侠网下载，游侠的一定能升级（用虚拟光驱安装的那种，ISO类型），安装升级补丁的话不一定要安装之前的版本，因为有覆盖版，在升级之前应该先看看你安装的版本是什么，看版本的话只要打开你安装的游戏目录，找到打开游戏的EXE文件，把鼠标停在上面，一般会显示版本，如果还没显示的话就点属性看看，最后还是强烈建议你去下载游侠网上面的，质量有保证，打补丁什么的都适合，盗版的东西一般只能将就玩，装MOD什么的很容易出错，祝你好运，解答完毕
