I have a fairly decent PC (6GB ram) and I still have issues running GTA V on my computer and I have no idea why. I can run other games just fine with 40+fps but GTA V gives me extreme stuttering. It used to lag, too, but I got a mod called "GTAV for low-end PCs" and now it just stutters anytime I do anything (such as driving over 20mph, which is most of the gameplay) also note that I do a computer restart and open only steam and GTA V when it finishes restarting. This is dumb and I just want to play the game i spent so much money on to work.
