Found better settings for my OnePlus 3! 720p, vulkan, all optimizations, 60fps, smooth, low graphics, no shadows, and turn off the auto graphic adjust in game to have the best experience ever! Temps remain the same as all other settings for me but this runs 60fps almost the whole time I am playing so its definitely the best setup I have found yet. Give it a try and let me know how this works for you.
