01.Introduction: FiveM vs. GTA Online
FiveM is a resource-intensive platform. It loads custom assets (cars, clothes) that haven't been optimized by Rockstar. Consequently, a PC that runs GTA V on Ultra might struggle significantly in FiveM.
In this guide, we will focus on configurations that handle the excessive polygons of unoptimized mods, helping to save your VRAM.

02.Chapter 1: Critical Graphics Settings
Grass Quality
Recommended: Normal
Ultra grass is the biggest FPS hog in rural areas like Sandy Shores. Set this to Normal to gain up to 20 FPS instantly.
Post FX
Recommended: Normal
This controls Bloom, Motion Blur, and HDR. At Ultra, it is very demanding. At Normal, the game looks cleaner and runs much faster.
Extended Texture Budget (The Bar)
Recommended: Half of VRAM
Found in the advanced graphics menu. Increase this until the VRAM usage bar turns green or yellow. If it turns red, you may experience textures failing to load (invisible city assets).
03.Chapter 2: Shadows and Reflections
| Shadow Quality | Normal/High | Very High uses expensive "PCSS" or "NVIDIA Shadows." Use "Sharp" instead. |
| Reflection MSAA | Off | Antialiasing for reflections is largely unnoticeable and very taxing on performance. |
| Water Quality | High | Normal makes water look poor; High is well-optimized. Very High simulates complex wave physics which is very demanding. |
04.Chapter 3: FiveM - Clearing the Cache
Perform this if you see flickering cars, bugged textures, or if the game crashes when joining a server.
- Close FiveM completely.
- Navigate to:
AppData\Local\FiveM\FiveM.app\data. - Delete the
cache,server-cache, andserver-cache-privfolders. - DO NOT DELETE the
game-storagefolder (these are the base GTA files, 50GB+). - Restart FiveM.
A1.Chapter 4: Population Density and Variety (CPU)
GTA V relies heavily on the CPU to calculate NPC and traffic AI.
- Population Density: 50% or lower.
- Population Variety: 0% (Low). This forces the game to load fewer distinct car models into RAM, reducing stutter.
- Distance Scaling: 100%. (Avoid reducing this or buildings will pop-in right in front of you).
A2.Chapter 5: Tessellation and DirectX
- DirectX Version: Use DX11. DX10/10.1 are legacy versions and prone to visual bugs. - Tessellation: Normal or Off. This only adds relief to trees and rocks; in RP cities, its impact is negligible.
A3.Chapter 6: commandline.txt
Create a commandline.txt file in your root GTA V folder with:
-ignoreDifferentVideoCard
-disableHyperthreading
-high
Note: -disableHyperthreading can help with older Intel CPUs (4th to 9th gen i5/i7). Do not use this on modern Ryzen processors.
A4.Chapter 7: GTA settings.xml (Fine Tuning)
Located in: Documents\Rockstar Games\GTA V\settings.xml.
You can disable shadows entirely by changing ShadowQuality value="0" (the in-game menu only goes down to 1).
This provides a massive FPS boost, though the game will lack visual depth. Use this only on "potato" PCs.
Chapter 8: Optimized RP Cities
Many Roleplay servers utilize "FPS Boost" features that remove non-essential props (trash, utility poles, fog).
If your FPS is low, look for servers offering a "Potato Mode" or use the /fps command within the game if available.
Chapter 9: PVP Graphics Mods
For competitive PVP, seeing through bushes and removing smoke effects is a priority.
Consider graphics mods like NVE (Low Version) or CitizenFX Vision which clear the atmosphere and remove distance fog, drastically improving enemy visibility.
Chapter 10: FPS Limit (Engine Stability)
The GTA V engine (RAGE) begins to experience physics bugs above 188 FPS.
Cars might behave erratically or fly into the air.
If you have a high-end PC, cap your FPS between 160-180 to avoid these issues during Roleplay.
