- Update your graphics drivers. Genuinely, do this first.
- Cap your frame rate. Uncapped frame rates cause crashes on some setups.
- Lower texture quality one notch. FiveM servers stream a lot of custom assets and video memory runs out quietly.
- Disable overlays: Discord, Steam, GeForce Experience, MSI Afterburner and RivaTuner are all known offenders.
- Verify your GTA V install through its launcher.
- Remove any single-player mods from your GTA V directory. They do not coexist with FiveM.
