不過去掉optimize的影響的話，這個部份影響不會超過5%。
比如說Toms引用的這段：

xxx @ NVIDIA just pointed out that filling textures with a constant color/alpha might cause more pixels to be written to the framebuffer (passing alpha test), which could affect performance. Totally forgot about that one and I should probably change the code to leave the alpha channel alone for our next generation engine

X800Pro stock 8XAF(form CP) forced bilinear @1600x1200
fps：85.9(normal)-->74.6(colored mipmap)
你認為有沒有超過5%呢?…
而且，除了UT2003/2004外…我不知道還有那個「引擎」的遊戲可以開colored mipmap耶…
