iPad Pro Graphics Settings Question (120fps)

I have the latest iPad Pro, which the latest update now allows 120fps to be enabled. That’s great, but with everything maxed out it is a laggy mess. So, has anyone experimented with the best iPad settings to get 120fps to work smoothly?

Without 120fps I think the game is perfectly smooth at 60fps with everything else maxed out. I suspect a couple small adjustments could make it work. Anyone have a formula that works for them?
