Check if your computer is running any disruptive background processes, or if there is some kind of I/O bottleneck (for example, if you fill up a hard disk or SSD, write performance will suffer). On Linux you can do this by installing htop and iotop, on Windows you can use this using the Task Manager, I'm not sure about Mac. You can also use something like Fraps (https://fraps.com/ https://fraps.com/) to check your framerate. Also, what graphics cards and cooling solution do you have? If the computer is not getting adequate ventilation and there is a buildup of heat, then the processor may throttle, resulting in dropped frames.
