It is possible. Back in 2012 when Nexus were getting more and more popular with BC2 at one point I remember, Domo had enabled 64-player servers but I don't know how or why isn't it here too. I think there was some problem with their files and they lost them and by then Domo wasn't working on it anymore, got so many side-projects to do that he couldn't stay concentrated. But in my opinion, the maps in the game are not made for 64 players, let alone 128. This game was made more with consoles in mind (12v12) and the PC variant (16v16) sometimes does feel a bit too crowded.
P.S - This is all based on memories so I dunno if it was really Domo who made it or NoFaTe back then. As far as it goes, it could've been even me
Nope
