英文原文 :
• Ultra settings have been disabled for users running 32-bit versions of Windows unless using the /3GB OS startup switch
只有用 64位元系统才能开启 Ultra 画质 (Ultra 设定会用超过2GB 的 内存, 因为32位元系统每个执行程式上限最多只调能用2GB 内存,强行运用32位元系统运行 Ultra 会出现不稳定或死机, 而 64位元系统没有这个限制, 所以32位元 window 是不适合的 )
用32位元 window 的, 除非用了 3GB OS startup switch
(但3GB OS startup switch 的方法只对应以下平台.........所以 window XP 是不行的)
* Windows 2000 Advanced Server
* Windows 2000 Datacenter Server
* Windows Server 2003 Standard Edition
* Windows Server 2003 Enterprise Edition
* Windows Server 2003 Datacenter Edition

Restricting the usage of ultra settings for 32-bit users has nothing to do with performance. It has nothing to do with 'lag'. Ultra settings require more memory than 32-bit OS's can provide access to for a single application.
I'll try to explain this in more detail.
First of all, DOW2 Ultra settings mode can consume more than 2GB of RAM. That means your game will likely crash if you do not fulfill this requirement.
32-bit Windows operating systems can handle up to 3.25GB-ish of RAM, maximum. You can have 4GB installed, but 3.25GB or so is all that will be recognized. A single application cannot access more than 2GB-ish from that amount. So you have 3.25GB usable, but any single program can only access about 2GB of it at once.
The /3G switch lets an application access up to around 3GB at a once, so this fulfills the ultra settings requirement. There are compatiblity issues with this switch and various drivers, again google about the switch before enabling it.
64-bit Windows operating systems have none of these problems, so if you have more than 2GB of physical RAM, you are good to go.
