GTA V's PC version is lauded as the game's definitive edition. While the popular and versatile Rockstar Editor has since made its debut on current-gen consoles, the PC version still enjoys the advantage of the superior visuals, modding and tweakability.

From tweaking system settings, overclocking hardware and configuring your display, you can do a dozen different things to get a better FPS.
