Although Internet Explorer 11 is supported, we do not recommend using it to connect to Sage X3 products. Internet Explorer 11 technology (2013) might exhibit performance issues with Sage X3 in selections and navigation, with a user interface perceived as much slower than with other browsers.   

WARNING: Customers who need to use IE11 for compatibility reasons should not expect a guarantee of performance comparable to recent browsers such as Chrome or Firefox. Sage will not fix perceived performance issues specific to IE11 as the reasons are not related to the Sage X3 platform.
