I think this is what you mean?
This is an interesting topic! I was happily playing the sim on a OneXPlayer until I bit the bullet and went full-desktop-ninja for my hobby. For the size and more impressively the low power usage, it is incredible!
I did use an eGPU though (RTX2070) as the OneXPlayer has Thunderbolt and the poor little Iris XE inside could not really manage anything much unless render res was at like 30-40% (still playable, but didn’t look good on that super hi def 8.4 inch screen!
