Hello, I am also facing the problem with WebGL for three.js in IE. The error it is showing is webgl content is taking too long to render on your gpu so currently switching to software rendering. In https://stackoverflow.com/questions/42092214/webgl-rendering-time-limit-internet-explorer-11 this site they are saying that make your calls less. But I need those models runtime at a time. How to tackle this problem. Can anybody please answer, if faced the same. I have WebGL 77 version and IE 11. Thank you.
