IE11 cannot handle the WebGL version of Google Maps. For example, try dragging the map around on this page:
https://developers.google.com/maps/documentation/javascript/examples/map-simple
If you visit maps.google.com, however, you will see it uses lite mode (canvas) and it works much smoother. If visiting that page doesn't use canvas mode automatically, go to this URL:
www.google.com/maps/preview/?force=canvas
I'm developing against the Maps javascript API, so I need to know how to force this mode so my IE11 users aren't met with a terrible experience.
