I'm playing with sd636 smooth extreme setting with a lil tweak at the dev option where i turn off all animation, gestures and hibernate all app using greenify app, I can get 60fps easily on tdm or playing classic using gfx tool. Frame drop only happen whn i land in crowded places and run across smokes. Still enjoying poping some heads tho. I herd the new hdr smooth setting on sd855 phones really drain their battery quickly pretty sad
