I'm currently unable to use my gaming PC (not that that would be an improvement, the thing is 10 years old) and have been playing for about half a year on my surface pro 7.
CPU: Intel(R) Core(TM) i5-1035G4 CPU @ 1.10GHz, integrated graphics.
RAM: 8GB
FAF runs, but I'm running it at a much lower resolution than what my screen would natively run at. All settings are medium or low to further squeeze out any performance.
Games with up to 8 people usually work fine, anything more than that and it becomes iffy. Larger maps with 12 players means I'll be at -4 simspeed after the first hour.
