Regularly delete the cache folder in your FiveM Application Data. Old data from different servers can cause major stuttering. Step 3: FiveM In-Game Settings for "Extra Quality"

: Paradoxically, you kept Texture Quality on "High." Why? Because it keeps the cars looking sharp while shifting the load to your VRAM, preventing that muddy "PlayStation 1" look. The Turning Point

, where every custom script and high-poly car model fights for your RAM, "Extra Quality" usually means "Extra Lag."

Keep this at roughly 30-50%. Any higher and your CPU will struggle to keep up with the world streaming.

FiveM is notoriously CPU-intensive. Unlike single-player GTA V, FiveM servers run hundreds of scripts simultaneously. A "memory leak" in a housing script or a poorly coded speedometer can tank your FPS from 144 to 30 instantly.
