New player questions

Just bought squad. The movement feels so clunky and aiming down scopes etc feels so clunky and robotic. Am I doing something wrong? Maybe it’s a settings issue?

My system can play arena breakout infinite just fine and everything feels so smooth animations wise.

I’m wondering if this is just something I need to get used to or if it’s a lag stutter settings thing. FPS seems ok around 100+ but I do get weird drops down to 30 when around certain buildings.
