侠盗猎车手4——来自GTAForums置顶贴的解决方案

　　However by doing what elecg2 tried, I got a huge performance increase,

　　不管怎样按照elecg2 的方法，我的显示效果有了显著提升。

　　Go to GTAIV folder, go into common, then shaders.

　　进入游戏目录-common-shaders

　　Backup everything in there <- !!!

　　备份shaders里面所有的文件!!!

　　Then copy the contents of win32_30_atidx10, and paste them into win32_30_nv8. Or just rename the folders, whatever makes you happy.

　　然后把win32_30_atidx10文件夹中的文件覆盖到win32_30_nv8中，或者把这些文件夹改名，随你高兴。

　　That gave me a significant performance boost and I have no graphical problems or abnormalities. Try it, if it causes you problems or decreased performance then just put it back to normal. With these steps you can get your game running beautifully in no time, or at least better than before.

　　这给了我可观的显示效果的提升(不知道是指帧数还是画面)而没有任何的显示问题或者反常。试试这个吧，如果这个引起问题或者减低你的显示效果，那么把备份的覆盖回去就行了。按照以上步骤，你可以是你的游戏画面马上变得非常漂亮，或者至少比以前好。

　　Enjoy.

　　*Ill be adding screen shots tonight.

　　Please Sticky This, I'm tired of people complaining when the answer is right under their nose.

　　请把这帖子置顶，我已经厌倦了人们不停抱怨，而答案就在他们眼前。(这也是我想说的)

　　To do a test to actually see if you get any gain from this start your game with 800x600, rest settings how you want them, but start the game in windowed mode. Manually drag the window to your screen size. See if you have a performance increase there, if so. Then doing this big mess of text will help you achieve what you achieved there without having to start the game in windowed mode and manually resize it, thats all this thing does. If you don't get a gain from it then clearly this is no use to you. But it is use to a lot of people.

　　做一个测试看看这个方法是否对你有用：窗口模式启动，分辨率设置为800X600，然后其他的按照你的需求设置。手动将窗口拉到你的显示器尺寸。看看显示效果是否有提升。如果有，那么按照上面那一大坨屎一样的文字来设置会帮助你获得这样的效果而不需要使用窗口模式和手动调整大小。如果你无法从中获得提升那么显然这个方法对你没用，但是这对很多人是有用的。(至少对我有用)
