Shader Compile Performance


Recommended Posts

I'm working on a project in PIXI v4, using AdvancedBloomFilter. It works great after it loads. But right when it first renders, there's a performance hit. Chrome Devtools shows the delay in AdvancedBloomFilter's apply function, which deeper down has a long call to getShaderParameter. My understanding is that this is happening at compilation time for the shader, querying for success. What's the best approach to improve performance here? What could be causing the delay? Is it expected? This delay is causing stutter at a crucial moment. If the delay is unavoidable, is there a strategy for pre-loading? Should I set the stage, add the filters, and just keep it at alpha=0 until I'm ready for it? Any advice greatly appreciated.
