High CPU occupancy |
---|
- Try to reduce actor count ( less actors == less processing) - Delete any actors that are not visible, or move them off stage - Use TextureAtlases ( greatly reduces OpenGL driver calls to glBindTexture - Optimise / reduce any constraints used |
High GPU occupancy |
---|
- Reduce visible actor count ( == less draw calls) - For 2D UI graphics which require no z sorting use @code Actor::SetDrawMode( DrawMode::OVERLAY ); // In this mode depth testing is turned off and order is determined by the hierachy (depth-first search order). @endcode - Use TextureAtlases ( reduces state changes in the GPU) - Use compressed textures - Use lower quality textures, e.g. smaller, lower number of bits per pixel - Use Dali::NinePatchImage where possible. - Avoid using too many textures which contain alpha and require blending - Avoid using too many Dali::Layer with depth testing enabled. Otherwise the layer has to clear the depth buffer. - Optimise any shaders used. Pixel shaders should be kept as lean as possible. |
