OfflineTileMap speed

RickJones — Fri, 31 May 2013 14:11:53 GMT

In 2.x, the offline basemap tiles loaded smoothly and fast. ( < 1 second from zoom to rendered).

In 10.1.1, the sample Offline project is very laggy, with some tiles taking 5 seconds to draw. I can see the background grid sometimes.

Is there some configuration I need to do in XCode?

Are you running the sample on the device? or the simulator?

If device, which one?

I'm running on the simulator on a Mac Pro.

The simulator, unfortunately, does not give a good indication of the performance of our new display pipeline. For example, in the places where we use hardware acceleration, the simulator relies on software to interpret those instructions.

Could you try running on a physical device and see if you still see a performance difference between the old and the new?

You are correct. It's smoother on the iPad.

I don't recall that much difference in 2.x on the simulator.

Good to know.

In 2.x, we used a different display engine that was entirely cocoa based. At 10.1.1 we moved to a native display engine that uses OpenGL ES
