Threejs Crash Problem

Threejs examples never crash even if I open 50 different animated examples at the same time. I created a scene and it is crashed when try to open same example in 2 - 3 tab in same time. What is the different? Is it about Lightmap or is there a role on the server?

I am getting context lost error.

Scene not render each time. It is render just when controller changed so not use GPU all time.

Can we detect why context lost? Is it have a way for get more detail about problem.

I’ve experienced this when the GPU runs out of memory. This is almost always due to huge textures…
