There really isn't much you can do if you want to stay at current settings.You'd have to change the GPU, but they are usually soldered to the motherboard so you have to go through the manufacturer. Or you can get a slight boost by overclocking RAM, not so much anything else as laptops overheat at default settings. And since it is a laptop built by Asus, the BIOS is probably flashed to be locked, but maybe not-never had an Asus laptop.
If yo want 60FPS, either lower the settings or lower the resolution or both.
