#### <a class="anchor" id="bkmrk--0"></a>Use Texture Compression

<div class="contents" id="bkmrk-per-vertex-lighting-"><div class="textblock">- Per-vertex lighting is less expensive than per-fragment lighting.
- Use as few lighting sources as possible (usually one light source is enough).
- Use simplified, tailored lighting calculations.
- Use light ranges to reduce the illumination area.
- Pre-calculate your lighting effects by putting them into textures.
