Of course you can not only improve the graphics of GTA 5 with Mods, but also optimize the gameplay or even add new content. Here are some of the most interesting modifications.

Of course, GTA 5 is not too realistic in its original version and only poses wounds and co. About the life energy. For those who want something more sophisticated here, the Mod Gunshot Wound 2 is just right for them.
Here, wounds have more comprehensible consequences. For example, they can lead to bleeding, which in turn means the death of the character when they are too bad.
Likewise, the figures then have a certain pain tolerance. Any wound can cause the pain to become too strong and a character to faint.
Installing Gunshot Wound 2 requires ScriptHookV and ScriptHookVDotNet.
To install this modification you need OpenIV. Don't forget to track game stats and such with FPSTracker.
The Mod Pickpocket Script lets you rob in GTA 5 passers-by on the street.
As a pickpocket, you'll easily get a little money, but it could also be that a packet of cigarettes or maybe even the victim's smartphone ends up in your pocket.
The stolen property you can then bring to a fence to get rid of the stuff against cash again. Also for this mod ScriptHookV and ScriptHookVDotNet are required.
Simple Healthbar
With Mod Simple Healthbar you'll make gangster life in GTA 5 a little easier. This little change in the game adds life bars that are displayed above your opponents.
So you can easily see how many shots are still needed, so that your adversary is done or how many hits a bulletproof vest still endures.
To integrate the life bars in GTA 5, you need ScriptHookV.
Fine-Tuned Felony & Response
Thanks to the Mod Fine-Tuned Felony & Response, GTA 5 is again a bit more realistic. This modification revises various game content, such as the stealth system, the behavior of the police and the functioning of the Wanted level.
As a result, a fist fight on the street does not directly lead to your being sought by the police. You will not get a wanted star until a passerby has seen and reported a crime - just like in Red Dead Redemption 2.
Likewise, law enforcement in unfamiliar vehicles will not recognize you any faster and as soon as they can not see you anymore, your wanted level will drop faster.
Overall, the mod makes the game world of GTA 5 a lot more credible. Again ScriptHookV is necessary for the installation.
Crime and Police Rebalance & Enhancement
The Mod Crime and Rebalance & Enhancement for GTA 5 also provides more credible behavior for law enforcement, making it an alternative to Fine-Tuned Felony & Response. The crimes must first be reported as in the above-mentioned mod, before a cop is looking for you.
The use of mufflers usually means that no one gets a crime. The AI has been redesigned so that ordinary police officers are less dangerous and the one-star wanted level does not directly lead to their being shot at.
In addition, the officials first look at the last known position of your character, instead of directly knowing where you are.
