Why doesn't fixedupdate exist?

What we would like to do in Defold is to decouple physics simulation from rendering. It can sometimes make sense to have the rendering happen 60 times per second while the physics simulation happens only 30 times per second or at any other interval for that matter. The problem we’re facing is that we are not able to run the physics in a separate thread on HTML5. We may be able to do this in the future, but for now everything happens in sync in the engine.

Hi dear @britzl
Because of long time not using Defold I didn’t know you added fixed_update, I just see this function on default script and after searching I found this topic and after that This update topic as well. The question is: does it work well on HTML5 export in current version?
Thanks in advanced
