Humus今天公布他研发的ATi 3Dc纹理压缩技术演算demo，这个3Dc演示demo可以对比3Dc和常见的DXT5之间在画质和速度上的差异，可以让使用者对比3Dc和DXT5在压缩未压缩纹理上的性能。Humus今天同时公布一些测试数据：

No compression: 125fps

3Dc: 146fps (+17%)

DXT: 136fps (+9%)

3Dc & DXT: 158fps (+26%)

在去掉Shadowmap之后的性能：

No compression: 164fps

3Dc: 210fps (+28%)

DXT: 195fps (+19%)

3Dc & DXT: 239fps (+46%)

Humus今天公布的这个3Dc演示demo在X800系列图形芯片上缺省以3Dc模式运行，在R3xx和NV4x上缺省以DXT5模式运行，显然DXT5的画质要比3Dc差上大截。
