Thatimst3r touches on a number of techniques that will help you get the best performance for your game/realtime projects.
In this tutorial I go over 9 different things you can do to optimize your game within the blender game engine. Many of the concepts used can also be applied to any other game engine.
- Vertice count
- Texture size
- LoD for lights
- GLSL render panel
- Occluder objects
- Linking duplication
- Resolution + clipping
All of these concepts are explained in detail with working examples to try and help you better understand their benefits.
Hopefully this will be useful for anyone currently making a game, that is running poorly.
