GTA4对硬件要求bt的原因——软硬勾结zz

为何GTA4 PC版要求高得离谱？

答案：GTA4 PC版根本没有经过任何优化，纯粹就是糊弄人的移植。不相信？

看看这段代码：

SetRenderState(p,a,b)
RenderState22 1
SetVertexShader(p,a)
SetVertexShaderConstantF(p,a,b,c)

SetStreamSourceFreq(p,a,b)
SetStreamSource(p,a,b,c,d)
DrawPrimitive(p,a,b,c)
FontIndex 1,.

这么多次调用，就是干了一件事：显示了一个“Dave is not coming.”
稍微懂行的人，就会知道，实际上这件事只用这么几行就行了：

SetRenderState(p,a,b)
SetVertexShaderConstantF(p,a,b,c)
SetTexture(p,a,b)
SetVertexDeclaration(p,a)
SetStreamSourceFreq(p,a,b)
SetStreamSourceFreq(p,a,b)
SetStreamSource(p,a,b,c,d)
DrawPrimitive(p,a,b,c)

不过还不算完，上面的代码竟然在一桢中重复了足足五次！也就是，平白无故的多了15*5*8=600次Directx调用。
随便再NB的机器也跑不动。这还仅仅是显示几个字符，游戏程序其他地方的优化大家可以想象了

这样的代码完全是程序员故意的，是软硬勾结的最典型范例而已

楼主那里找到这些代码的？
哪个文件夹？。。。。。。。。。。。。。。。

本来就是这样~
都没指望PC版能卖多少

楼主是用ollydbg反编的? [汗水]

这是转自隔壁汉化组发的帖子。
昨天在隔壁看过。据说春节期间就能发布中文版了。

想了解用的是什么反编译软件?

想問一下這帖發了多少遍

看不懂，顶一下！ zzzzzzzzzzzzzzzzzzzzzz

恩,看过了,是3dm汉化组做汉化时发现的.

不是已經有人說過是假的嗎?????????

进来拿个分吧 小鸟一只 什么都看不懂..

如果是真的，，，有没有高手简化一下代码呢？

如果这是不能做到的事情，，，那么我们就继续装不知道吧。。。。。难道你还闹情绪不玩GTA吗？

要是有超级高手，可以从新写一遍代码就好了。哈哈
