There are many benefits and disadvantages to capping your FPS. Capping your FPS saves energy and resources on your computer. Keep in mind however that it is
not vsync and will not prevent screen tearing. Capping your FPS is best used when you are on a laptop, a computer that overheats easily, or a computer that is lacking proper cooling.
Capping your framerate can have a few benefits:
- Heat reduction
- Energy reduction (won't fry your laptops battery)
- Decreased noise (Fans aren't working as hard.)
If you have a solid build that has sufficient cooling, you don't need to worry about it. However if you are on a laptop, I would highly suggest that you do cap the frames to your monitors refresh rate.
