Openlayers 3 improving vector layer performance

I have a vector layer which is county boundaries for all counties in the US. When I add this layer to the map, the map becomes very slow when zooming in and moving around on the map when I am zoomed out to a certain extent, but performs Okay when I am zoomed in. I believe this is because of how much detail that is being drawn with all the county lines when zoomed out. Does anyone know of a way to force openlayers to draw a less detailed version of the vector layer when I am zoomed out to a certain extent? Also any other ideas to improve performance with detailed vector layers like this would be appreciated. Thank you!

You could try using an image layer with an image-vector source.

Here's an example:
