You can try the command Max_fps # (whatever number you want)
So for instance you want 200 Frames per second
In your case you can play all the smoothness @ max_fps 120
Check your temps, some cards get hot when producing a lot of frames.
but also when im in servers with like tons of people like 55 players one time i tend to lag when i face them as a group in the game is that normal?
or am i supposed to have 60 fps no matter how many players there are
