Although overclocking GPU can boost the in-game FPS, overclocking GPU differs from increasing FPS. Specifically, GPU overclocking is to adjust the GPU to work at a higher clock, while increasing FPS means allocating more CPU and RAM resources for a game to render out more frames per second for smoother gameplay. The most common method of GPU overclocking is to increase its clock at the expense of high temperature or even the hardware, while FPS increase is often achieved by closing background services and programs and amplifying the RAM. Hence, increasing FPS can be safer than GPU overclocking. But if you had no idea how to boost FPS, automatically overclocking GPU is also feasible to increase the FPS.
