IF YOU INSTALL EVERYTHING I HAVE HERE YOU WILL LOOSE 2-3 FPS TOPS USUALLY NOT ANY. THIS GUIDE IS DESIGNED TO HAVE LITTLE IMPACT ON YOUR GAME FPS WISE. I RECCOMEND CHECKING OUT THE 'REALISM' SECTION FOR NEW DOWNLOAD LINKS TO GREAT CONTENT.
I ADDED MANY MORE REALISM MODS, INCLUDING SOUNDS AND THE BEST CARS MADE FOR GTA V TO DATE. If I decide at some point to not update this I will say so here.
