App works great. The key to getting the perfect display settings is to either tweak all the settings yourself, keeping in mind that one doesn't try pushing the device too hard, or use the "zero lag + battery efficiency" option.
I am using LG G6 H870DS on Oreo, and I can testify that, HD+ resolution could be the perfect balancing point between the highest possible graphics, details, etc, and constant stable 25-35 fps.
However, the game will stutter ever so slightly when a bunch of players spawn, especially during the starting and jumping off the plane.
Thank you so much!
