Those with GeForce cards will be happy to know that Nvidia has released a comprehensive graphical tweaks guide for GTA 5.
Nvidia usually produces graphical guides for the big AAA games, and GTA 5 is no different. Their guides offer in-depth coverage of each in-game setting, how much they affect framerate, if they can be tweaked outside the game, and much more.
The GTA 5 guide can be found through here and you’ll need to give it a read if you want to make the most of out of your rig. A multitude of GPUs are covered, so don’t fret if you don’t own the latest and greatest.
