Three.js( R71 ) not working on IE11 windows 8.1

I am running R71 of three.js and it's not working on windows 8.1 ie 11 version : 11.096 Update versions 11.0.7 I get these warnings:

THREE.WebGLRenderer: OES_texture_half_float extension not supported.
THREE.WebGLRenderer: OES_texture_half_float_linear extension not supported.
THREE.WebGLRenderer: OES_element_index_uint extension not supported.

Then shader compiler errors.

Then a lot of :

WEBGL11057: INVALID_ENUM: drawElements: Only UNSIGNED_SHORT type is supported

It's working fine on IE11 on windows 7.

Any help would be greatly appreciated.

Looks like an IE issue not a Three.js issue. Three.js is just reporting that IE11 on Windows 8.1 with whatever drivers and GPU you have on that system doesn't support those extensions.

The INVALID_ENUM error is a direct consequence of IE11 on WIndows 8.1 not supporting OES_element_index_unit. With that extension any sample that needs it will fail. The one you're running needs it.

Not all samples will need it. OES_element_index_uint just means you can have 32bit indices instead of only the default 16bit indies.

Have you tried other samples? For example I'd expect this one to work without those extensions.
