为何GTA4 PC版要求高得离谱？ 想知道的进来看

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：

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

事实上我也看不懂:a33:

3DM在做汉化补丁的时候发现的

R*的丑恶嘴脸一览无遗啊

感觉
像一个word一个word的拼上去的.
其实,600行代码
完全足够把这句话组成一个点阵图印在屏幕上了

大概一个月前也听别人说过这个了.

看不懂啊～:a37:
