[OpenLayers-Users] HELP! OL 2.13: Google v3 and other layers not zooming "together"

[Andreas Hocevar]

Google Maps is integrated using the GMaps API, and there we cannot control
zoom animation. Your best bet is to turn off zoom animation for the map by
configuring your map with

    zoomMethod: null

Then you can also activate the OpenLayers hack to remove the GMaps
animation by turning the layer off during zooming. To do so, configure your
Google layer with

    animationEnabled: false

Andreas.
