Even when I create a new default project, I get less than 30 fps. I have tried deleting the default light, cube and plane, but it doesn’t help.
The profiler for a new project with those things deleted (so just the camera left) looks like this:
I’m on a slow computer (laptop with i5-4200U and Intel HD Graphics 4400), but I come from Three.js and am used to 60 fps with geometry, animations, lights and shadows, so I don’t understand what I’m doing wrong to make it so much slower even with a blank project.
What I have tried:
Three different browsers
Debug mode on/off
Prefer WebGL 1.0 on/off
It’s rather hard to diagnose any problems from those profiles, I’m afraid. Interestingly, the project from @TheDarkPrince looks like it’s rendering a depth pass, which is normally done for certain post effects or rendering soft particles. But without seeing the project, I don’t know for sure.
Does the slowdown happen if you run a published build of the project?
Does the slowdown happen if you open a new browser tab and paste the launcher URL into it?
Does the slowdown happen in other browsers?
