Depend on the mood, when I really want to play this kind of game yes... otherwise no; just a question of mood.
Moreover remember that is not even 60 steady, yesterday on 3 people server I shoot to a tree... drop from 120 to 75/80 for a few second; so I guess that when I do this on a full server I will reach 20 fps... good during an intensive firefight on a mobile phone game.
As in the game, the important is to reach the objective... and we will never reach it if part of the team start to say "30 fps is acceptable" like I recently read around on the forums, this kind of comments is the reason that a lot of game run bad on all PC.
Actually only the 7700k can give this range, there is something around the forum but I don't find the link, I remember something like 75 to 100 fps on a full 80 player server.
Happy to wait, as I said before even to the beta.
I repeat, is a game "from gamer for gamer" and if they need money they have only to ask, or if they need time they only have to release the game later.
The only thing I don't need is a fast paced mix between arma 3 (that is more slow than Squad and 60 rock solid could be acceptable) and a generic shooter full of people happy to have a 1000/2000 $ PC and play at "smooth" 50 FPS on a 100 hz monitor, in 2017/2018, using 1/2 core of a CPU... I like old thing but I have a limit.
This decision is in the hand of the community, a good tactical FPS, or a tactical FPS for consoles, where is better to set a 30 FPS cap.
Unfortunately, is a small team, with limited amount of money (don't know how much they have now in the budget but surely they're not a big company like EA or Ubisoft or any other, so no money to waste), with an engine under build (recently UE4 received an update), and they put a very very very incredible high goals (100 player in the same server, simulated Newtonian physics, with vehicle and maybe choppers and planes).
Personally... I like this, big goals, small team (compared to other company); but even if i like the project I would not become a super fanboy who accept a barely performance in exchange to a shiny chopper who can be personalized with a new fancy patch
Luckily for us, developers know what play a game is (multiplayer PvP, not single player or co-op, big difference) so I give them my trust.
Welcome to the club, normally 45-65 on full 80 people server (depending on the map and the situation) on a 5820K.
If I can, I prefer to play on a 50 players server where i can reach a good performance.
The focus on optimization will be for the beta and, to be honest, I don't think that the actual PC's could run the game at the final release because it will contain a lot of things and it will need a new good PC based on the best components.
