Grand Theft Auto V featured amazing graphics when it was released, but that was clear back in 2013. Naturally there have been a lot of technological advancements since then.
One modder named “Razed” decided to take advantage of them. After 400 hours of hard work, he created an incredible mod which actually combines improvements from several different existing mods: ReShade, ENB, VisualSettings and TimeCycle along with the VisualV mod. The result is almost photorealistic.
