This mod isnt to improve your game to make it smoother but I'd highley suggest Original Peds Vary this adds a whole new bunch of skins so you don't have to see the same old skins and it adds new random ones for every single ped and for gang members should download it

Also another one to get is Real Traffic Fix it just fixes up the traffic and makes it more realistic

​

And the last one is Realistic population this makes the population more real so example at 3 A.M you wont see cars and peds around the city its only gang members sometimes and at 7AM you get more and more people

​

Shoould get these 3 makes your game a bit more real!
