Touch panels, iPad, Air Manager, Spacedesk sanity check

What sort of GPU are you using to drive all of those screens. I have a 3060ti and had to downgrade my main monitor from 1440 Ultrawide to 1080 wide, in order to achieve more than about 15FPS when I use POPM with two 7" touch displays? Trying to find a way round that without spending lots of cash.
