Wait, nevermind, actually Boost FPS, u need to put it inside your FiveM Application Data, not the server one, i was putting it inside my server folder. Using it boosted my FPS from 244 to 264, some kind of 20fps in that specific scenario, btw, it makes your sky really bad with red colors, not really pleasing to the eyes, but if you are extremely needed in FPS it's actually not that bad.
