Look I do send a monthly bit of cash to downlord to help. Its not much but its what I can send on my humble musician lifestyle.
As for research it doesn't take much more than above brain-dead levels to know that peer to peer is over 15 years outdated. If I can play cs go with russians and have some lag than the I should be able to play FAF with mostly east of atlantic lobbies and have it be playable. These guys literally just point fingers at me and say "spy lags, fix it" and I have 550 mbps down and 500 mbps up with 12 ping to node. My internet could not possibly be more blingy. Streaming is not taking even 10% of that data rate.
The issue is one p2p branch is getting throttled by some node somewhere and the game doesn't re-route around that intermittency so then the slowest person by range to those players goes behind. Many times the player who is getting blamed is the one getting delay on this once removed. And since USA has largely all gotten bug eyes at cyberpunk 2017 and is going "wut do elo score?" I'm literally alone here. USA is a big country (and our neighbors north and south) so something scared them all away and this is it. Getting blamed for some shitty netcode.
Just buy some server space in France and build in an add portal on the lobby screen and FAF client. Should even out.
