Disable Texture Filtering

使用
Disable Texture Filtering
覆盖模式以查看纹理过滤算法是否是瓶颈。如果两个相邻的纹理像素之间的距离大于一个像素,纹理过滤允许插入(过滤)纹理对象的颜色。
如果应用程序的性能在使用
Disable Texture Filtering
技巧后得以提高,则表示纹理过滤算法可能是瓶颈。其原因可能是使用计算耗费大的纹理过滤,如高层次的各向异性过滤。
根据速度要求优先还是质量要求优先,可考虑采用较快的纹理过滤方法。由于各向异性过滤是速度最慢的方法,可考虑使用双线性过滤、线性过滤或甚至最近点过滤。可以通过修改基元的图形状态而不改变任何应用程序代码来测试不同过滤方法的性能效果和视觉效果。
