as a mac user, you most certainly do have a task manager. albeit it is called activity monitor. The best way to keep FPS steady is to use /maxfps X where x is the number where your machine can run all maps the most comfortably. There are many ways to reduce even more graphical features of the game by using a menu/script V-man made although you may not like the consequences of using it if you don't know what each function does. My recommendation is to just play where it is the most steady and cap it at that.
