侠盗4画质提升的简单方法效果明显绝对有效，大多数电脑都可以实现

tur110

侠盗四画面本身不太好，网上有很多提升补丁，看上去很华丽，但是很多朋友用了都会出现错误，和画面过亮问题，我也一样呀，所以我找了很多方法终于解决了，网上下载一个（GTA4低配置优化版ENB光影补丁0.815）这个程序把它解压覆盖游戏安装目录，这个补丁里面有个enbseries文档里面就是各种画质特效这里就不多说了大家自己打开按照自己的需要改吧，不改也可以，效果也比以前强的很多了，就是抗锯齿它里面是没开所以最好把那选也该下。
下面是我没有该他的效果的情况下运行的游戏图，画面阴暗度车身的反光下雨的地面效果都明显提升了，要是把效果再改一下，还有抗锯齿，画面还会跟好的。。。

下面是我改好的文件把它拷贝到新建文档改名然后覆盖enbseries源文件
