My nexus 6 was running buttery smooth before i updated it, and now seems rather choppy particularly with the camera and within chrome. Anyone else the same?

Camera, for sure. Slow to load (thats reported elsewhere too) and when taking HDR the CPU must be spiking to 100% to process those, leaving no more resource for allow the camera to function more normally so gets real jerky.

For me, i dont have an issue with Chrome, but I do run the Dev version, so maybe that's more optimised for Marshmallow.
