Introduction to FiveM cache corruption causes 80% of client-side

FiveM cache corruption causes 80% of client-side performance issues, including FPS drops, loading screen freezes, and texture glitches. This guide provides the exact steps to clear your FiveM cache safely without losing critical game files.

What Is FiveM Cache and Why It Causes Problems

FiveM cache (Official FiveM Documentation) stores three types of client-side data:

• Browser Cache: CEF/Chromium temporary files (300MB-2GB)
• Server Cache: Downloaded resources per server (100MB-5GB per server)
• Subprocess Cache: Script compilation artifacts (50-500MB)

When these files become corrupted or outdated, they trigger specific issues:

• FPS drops and micro-stuttering from broken asset references
• Infinite loading screens when corrupted resources fail to load
• Missing textures and invisible objects from incomplete asset downloads
• Random crashes caused by conflicting cached data
• Excessive storage usage as cache folders grow unchecked

      When To Clear Your FiveM Cache

      Clear your cache immediately if experiencing:

      • Consistent FPS below your normal baseline (>10 FPS drop)
      • Loading screens exceeding 90 seconds
      • Texture pop-in or missing map elements
      • Crashes when joining specific servers
      • FiveM consuming >10GB storage space

      Performance impact: Cache clearing can improve FPS by 15-30% and reduce loading times by 40-60% on corrupted installations.

      Pre-Clearing Safety Checklist

      CRITICAL : Follow these steps before clearing cache to

      CRITICAL: Follow these steps before clearing cache to prevent data loss:

      1. Close FiveM completely – End all FiveM.exe and CitizenFX processes in Task Manager
      2. Backup custom configurations if you have:
         • Custom key bindings in %LOCALAPPDATA%\FiveM\FiveM.app\data\client.lua
         • Saved server favorites
         • Custom UI modifications
         • Note your current FiveM version for troubleshooting

      Method 1: Safe Manual Cache Clear (Recommended)

      Step 1: Navigate to FiveM Application Data

%LOCALAPPDATA%\FiveM\FiveM.app\data\

Alternative access methods:

• Right-click FiveM desktop shortcut → “Open file location” → Navigate to data folder
• Windows + R → Type %localappdata% → FiveM → FiveM.app → data

Step 2: Identify Cache Folders

You’ll see these folders in the data directory:

├── cache/
│  ├── browser/  (DELETE)
│  ├── subprocess/  (DELETE) 
│  └── game/  (KEEP - Core game files)
├── server-cache/  (DELETE)
├── server-cache-priv/ (DELETE)
├── nui-storage/  (DELETE)
└── [other folders]  (KEEP)

Step 3: Delete Specific Cache Folders

Delete ONLY these folders:

• cache/browser/
• cache/subprocess/
• server-cache/
• server-cache-priv/
• nui-storage/

NEVER DELETE:

• cache/game/ (Contains 4-8GB of core GTA V assets)
• server-cache/game/ (If present)

Step 4: Restart FiveM

Launch FiveM normally. First startup will take 2-3 minutes as cache rebuilds automatically.

Method 2: PowerShell Automated Clear (Advanced)

For users comfortable with scripts, this PowerShell method provides precise control:

# FiveM-CacheClear.ps1
$fivemPath = "$env:LOCALAPPDATA\FiveM\FiveM.app\data"
$cacheItems = @(
  "cache\subprocess",
  "cache\browser", 
  "server-cache",
  "server-cache-priv",
  "nui-storage"
)

# Terminate FiveM processes
Get-Process | Where-Object {$_.ProcessName -match "FiveM|CitizenFX"} | Stop-Process -Force

# Clear cache with size reporting
$totalFreed = 0
foreach ($item in $cacheItems) {
  $fullPath = Join-Path $fivemPath $item
  if (Test-Path $fullPath) {
  $size = (Get-ChildItem $fullPath -Recurse -ErrorAction SilentlyContinue | 
  Measure-Object -Property Length -Sum).Sum / 1MB
  Remove-Item $fullPath -Recurse -Force -ErrorAction SilentlyContinue
  Write-Host "Cleared: $item (${size:F1}MB)" -ForegroundColor Green
  $totalFreed += $size
  }
}
Write-Host "Total space freed: ${totalFreed:F1}MB" -ForegroundColor Cyan

To use : Save as .ps1 file, run PowerShell as

To use: Save as .ps1 file, run PowerShell as Administrator, execute script.

Post-Clear Verification and Optimization

Expected Results After Clearing

• First launch: 2-4 minute loading time as cache rebuilds
• Storage freed: 2-15GB depending on cache size
• FPS improvement: 15-30% increase typical
• Loading times: 40-60% reduction on server joins

Performance Benchmarking

Test these metrics before/after cache clearing:

Benchmark Locations (FiveM):
- Los Santos Airport (high asset density)
- Legion Square (CPU-intensive NPCs)  
- Mount Chiliad (draw distance test)

Record:
- Average FPS over 60 seconds
- 1% low FPS (frame time consistency)
- Server join time from launch

Advanced Troubleshooting

Cache Clearing Didn’t Fix Issues

1. Verify GTA V installation integrity:
   • Steam: Library → GTA V → Properties → Local Files → Verify
   • Epic Games: Library → GTA V → … → Verify
   • Check FiveM log files in %LOCALAPPDATA%\FiveM\FiveM.app\logs\
     • Look for asset loading errors
     • Note script compilation failures
     • Update graphics drivers – Outdated drivers cause 40% of remaining issues
     • Test with minimal mods – Remove custom scripts/maps temporarily

Cache Corruption Prevention

• Clear cache weekly if playing on 5+ different servers
• Monitor cache size – Alert when exceeding 8GB total
• Avoid force-closing FiveM during resource downloads
• Keep 15GB free space on FiveM drive for optimal cache management

Storage Optimization Tips

Cache Size Management

Average cache sizes by usage pattern:

• Casual player (1-2 servers): 1-3GB
• Regular player (3-5 servers): 3-8GB
• Power user (10+ servers): 8-15GB

Storage warning signs :

Storage warning signs:

• Cache folder >20GB (indicates corruption)
• Individual server cache >5GB (corrupted downloads)
• Browser cache >2GB (CEF memory leaks)

Automated Maintenance

Create a scheduled task for weekly cache clearing:

@echo off
taskkill /f /im FiveM.exe 2>nul
taskkill /f /im CitizenFX.exe 2>nul
timeout /t 5 /nobreak >nul
rd /s /q "%LOCALAPPDATA%\FiveM\FiveM.app\data\cache\browser" 2>nul
rd /s /q "%LOCALAPPDATA%\FiveM\FiveM.app\data\cache\subprocess" 2>nul  
rd /s /q "%LOCALAPPDATA%\FiveM\FiveM.app\data\server-cache" 2>nul
rd /s /q "%LOCALAPPDATA%\FiveM\FiveM.app\data\server-cache-priv" 2>nul
rd /s /q "%LOCALAPPDATA%\FiveM\FiveM.app\data
ui-storage" 2>nul
echo Cache cleared successfully!
pause

Common Mistakes to Avoid

Critical errors that cause data loss:

1. Deleting cache/game/ folder – Forces 4-8GB re-download
2. Clearing cache while FiveM running – Creates file locks and corruption
3. Using generic “temp cleaner” software – May delete essential FiveM files
4. Clearing Windows temp folders expecting FiveM fix – FiveM cache is separate

Alternative Solutions

If cache clearing fails to resolve issues:

Hardware-related fixes:

• RAM: Minimum 16GB for optimal FiveM performance
• Storage: SSD installation improves loading by 70%
• CPU: FiveM is CPU-intensive, requires 4+ cores

FiveM-specific optimizations:

• Launch parameter: -heap 4096m for 16GB+ RAM systems
• Graphics settings: Lower texture quality if VRAM limited
• Network optimization: Use ethernet over WiFi for server stability

Security and Privacy Notes

Data handling during cache clearing:

• No personal data stored in cleared folders
• Server join history preserved in separate config files
• Screenshots and recordings unaffected by cache clearing

FAQ

Q: What does clearing the FiveM cache do?
A: It removes temporary client assets that can cause crashes, texture glitches, or stutters.

Q: When should I clear it

Q: When should I clear it?
A: After frequent crashes, streaming bugs, version conflicts, or after big server updates.

Q: Which folders are safe to delete?
A: In FiveM’s data directory, delete cache/ and cache_priv/ only. Do not delete GTA files.

Q: Will I lose settings or keybinds?
A: No. You’ll re-download server assets on join, but GTA/FiveM settings remain.

Q: Does clearing cache improve FPS?
A: It can fix stutters from corrupt assets. It’s not a guaranteed FPS boost but stabilizes frametime.

Q: Can I clear while FiveM is running?
A: No. Exit FiveM first.

Q: Do I need to verify GTA files after?
A: Only if you suspect base-game corruption.

Q: Can I automate cache cleaning?
A: Yes, use a small batch/PowerShell script to remove cache folders before launch.
