Texture Unit Load

The Texture Unit Load metric represents the percentage of the time that the texture units are busy.

Improving Performance

Use the following techniques to improve the texture sampler performance:

  • Reduce the size of textures by using a lower resolution or lower color precision, such as RGBA4444 instead of RGBA8888.
  • Use texture compression to reduce the amount of memory to transfer textures, especially using PVCRT or PVCRT2 textures.
  • Use mipmapping, so that smaller textures (mipmaps) can be used.
  • Reduce the number of textures in the scene.
  • Use a different filtering algorithm. For example, anisotropic filtering is more expensive to compute than a simpler algorithm, such as bilinear filtering.
