#2 – Rendering Tiers

WPF applications automatically examine graphics card capabilities at runtime and assigns a rendering tier value, indicating what functions can be performed by the graphics card.

  • Tier 0 – No hardware acceleration, all rendering done using software
  • Tier 1 – Some hardware acceleration available.  DirectX version >= 9.0.  Hardware acceleration for:
    • Radial gradients
    • 3D lighting calculations
    • Text rendering
    • 3D anti-aliasing
  • Tier 2- Most features use hardware acceleration.  DirectX version >= 9.0

To determine the current rendering tier:

 int renTier = (RenderCapability.Tier >> 16);
 MessageBox.Show(string.Format("Tier = {0}", renTier));
