if (this._webGLVersion > 1) {
    this._caps.instancedArrays = true;
else {
    var instanceExtension = this._gl.getExtension('ANGLE_instanced_arrays');
    if (instanceExtension != null) {
        this._caps.instancedArrays = true;
        this._gl.drawArraysInstanced = instanceExtension.drawArraysInstancedANGLE.bind(instanceExtension);
        this._gl.drawElementsInstanced = instanceExtension.drawElementsInstancedANGLE.bind(instanceExtension);
        this._gl.vertexAttribDivisor = instanceExtension.vertexAttribDivisorANGLE.bind(instanceExtension);
     else {
        this._caps.instancedArrays = false;

Here is this check it sets this._caps.instancedArrays to false, so it detects correct that extension doesn't exist

@Deltakosh I think I found what is wrong, inside Mesh -> render function there is check "var hardwareInstancedRendering = (engine.getCaps().instancedArrays !== null) ..... "  but "engine.getCaps().instancedArrays" is never null its true/false. Will check if there are other places where it is used.
