PC版GTA4游戏设置的误区和优化（官方）以及以及PC版在游戏性上的部分升级

直接把设置调成最高效是不正确的，这样反而会使系统负担过重而被迫关闭一些效果，其实中校就可以比家用机效果好了，参照下面的说明设置将会得到更好的运行效果。如果你配置足够牛当然可以最高，不过目前这样的机器不多，所以感觉游戏性能有问题的都来看看

首先是分辨率 360是1280*720 ，PS3是1024*600， PC最高达2560*1600

Rockstar told us that the equivalent vehicle density featured on the console versions would have been just 33 per cent
vehicle density选项，主机版是 33(最高100）

Render Quality
Medium settings are recommended for most users and will provide filtering beyond what the console versions can execute.
Render Quality 选项调成中等效果就就比主机版好（就是说主机版是low）

View Distance
A setting of 22 or more will provide PC users an enhanced experience over the console versions.
View Distance 选项调成 22 (最高100） 效果就比主机版好（就是说主机版22以下）

Detail Distance
A setting of 10 would be the equivalent to the performance on a console.
Detail Distance调成10(最高100）就能有完全和主机版一样的表现

Shadow Density
These shadows are exclusive to the PC version and can have a major impact on CPU and GPU performance.
某些阴影PC版特有，调成1(最高16）以上就能更好。

* PC version was worked on during the development process of the console versions, with a team of about 50 members.
＊ PC版是在游戏机版进行开发的过程中开始的，开发团队大约50人。
