Video playback resolution in Photoshop CC

This just in from @julieannekost: "Photoshop CC has added various resolutions to playback video. The default is 50% and other options are 25% and 100%. Setting a lower resolution can increase playback performance when working with high resolution video (in previous versions, Photoshop auto-dropped the resolution for faster playback). To select the playback resolution, click the gear icon in the Timeline panel. Note: the Loop Playback check box also appears in the gear menu."
