Multiplayer First Person Shooter Kit

How well optimized is the networking/replication of this FPS pack? Would you say if we’re trying to make a competitive esports FPS shooter that has AAA performance (not quality, just performance) that would need to further tweak and improve?

Oh, and options to see FPS, mouse sensitivity and aim type? Currently the aim/crosshair isn’t fixed to the gun models and when turning quick the model etc… lag behind. I’d prefer them to stick in place and have no effect when moving my aim around. Another issue is the input in aiming and looking around feels laggy and delayed as opposed to direct input! Any reasons?

Thanks in advanced!
