This enum describes what should be done on the render target when it is activated (loaded).
When the GPU starts rendering into a render target, this setting specifies the action that should be performed on the existing contents of the surface. Tile-based GPUs may get performance advantage if the load action is Clear or DontCare. The user should avoid using RenderBufferLoadAction.Load whenever possible.
Please note that not all platforms have load/store actions, so this setting might be ignored at runtime. Generally mobile-oriented graphics APIs (OpenGL ES, Metal) take advantage of these settings.
|Load||When this RenderBuffer is activated, preserve the existing contents of it. This setting is expensive on tile-based GPUs and should be avoided whenever possible.|
|Clear||Upon activating the render buffer, clear its contents. Currently only works together with the RenderPass API.|
|DontCare||When this RenderBuffer is activated, the GPU is instructed not to care about the existing contents of that RenderBuffer. On tile-based GPUs this means that the RenderBuffer contents do not need to be loaded into the tile memory, providing a performance boost.|
