Hi there, I wanted to implement the Reaction-Diffusion Algorithm and notices that I can’t get past 4 FPS. (JS implementations have typically a stable 60 FPS) How it should look like after a couple of seconds: [image] My Implemenation So why is Elm/WebGL that slow? How can i improve the calcula…

The example you linked performs very well because it runs the Gray-Scott algorithm on the GPU, rather than the CPU. It uses a feature of WebGL where it renders to a texture. Elm doesn’t expose an API to do this so I don’t think it can be written with pure Elm at this point.

Quick update: I now believe that it has nothing to do with WebGL. I’ve created a new Ellie. I’ve replaced the Dict with an Array → im now getting 14 Frames locally, 7 in Ellie. Also i added a way to skip frames (renderEvery on line 55). If this would be a WebGL issue, then the frames should not c…

@Lucas_Payr on WebGL performance, read the “Making the most of the GPU” section of the package docs webgl 1.1.3 that is also linked from the Mesh docs. In the nutshell, WebGL API in Elm is not meant for creating meshes in the view on each frame, because each time such mesh would have to be uploaded…
