記得毛毛哥跟弟弟我說過
fx5700比起5600多了UltraShadow和The CineFX 2.0
而5800並沒有這兩個技術
於是小弟跑去找了資料
"CineFX 2.0 still features vertex and pixel processing engines with support for long shader programs and advanced programming techniques, but doubles the performance of floating point pixel shading operations over the GeForce FX 5800 Ultra"
而ultrashadow對於陰影的表現又有很大的加速
