Black Desert’s engine stores a significant amount of local data in the UserCache folder, including character-specific UI positions and, more importantly, cached effect shaders for every class you encounter. Over time, this cache can become bloated or corrupted, leading to micro-stutters when the game tries to call an outdated effect. By manually purging the cache and then locking in optimized settings through the GameOption.txt, you can achieve a much smoother combat experience where skill transparency and effect density are perfectly balanced for high-performance play.
Hardware Compatibility & Expectations
- Competitive PvP Players: Essential for maintaining high FPS during large-scale sieges where 50+ players are using skills simultaneously.
- Low-to-Mid Range CPUs: BDO is heavily CPU-bound. Reducing the “Effect Load” on the CPU by cleaning the cache directly improves minimum 1% lows.
- Storage Speed: Players with older SATA SSDs or HDDs will see a massive reduction in “loading stutters” after a fresh cache rebuild.
Backup and Preparation
Before modifying any files, you must ensure your UI settings are backed up to the Pearl Abyss cloud, as clearing the local cache can reset some UI elements.
- Log in to BDO, go to Settings > Setting Archive, and click Upload.
- Completely exit Black Desert Online and the Launcher.
- Navigate to your Documents folder.
- Copy the
Black Desertfolder and save it as a backup on your desktop.
File Location
The UserCache and primary configuration files are located in your local Windows user documents: C:\Users\%USERNAME%\Documents\Black Desert\
Best Config Settings & Cache Purge
To optimize your skill effects, follow this two-step process:
Step 1: The Cache Purge
Inside the Black Desert folder, delete the following folders:
- UserCache (This contains the skill and UI cache).
- Cache (Temporary engine data).
Step 2: GameOption.txt Optimization
Open the GameOption.txt file in the same directory and ensure these specific lines are set for competitive combat:
removeOthersEffect = 1
removeFarawayEffect = 1
effectFrameOptimization = 1
selfPlayerEffectOptimization = 0
otherPlayerEffectOptimization = 1
effectOpacity = 70
Key Parameters Explained
| Parameter | Recommended Value | Impact |
| removeOthersEffect | 1 | Disables non-essential skill effects from other players (retains CC cues). |
| effectFrameOptimization | 1 | Scales the frame rate of skill effects to match your current FPS. |
| effectOpacity | 70 | The “Sweet Spot” for visibility; high enough to see animations, low enough to see the ground. |
| removeFarawayEffect | 1 | Stops the engine from rendering skill particles beyond your immediate area. |
| UserCache Purge | Delete Folder | Forces the game to re-cache only the currently used class effects. |
In-Game Settings vs. Config
After clearing your cache and restarting the game, apply these in-game “Optimization” settings for the best results:
- Effect Optimization: Turn this ON and slide it towards “Performance.”
- Hide Other Adventurers: Use Shift + F5 during World Bosses or Sieges to clear CPU overhead instantly.
- Upscale: Use AMD FSR (Balanced/Quality) if you are GPU-bound; it significantly reduces the cost of rendering transparent particles.
- Low Power Option: Always OFF. This setting throttles the engine and causes severe combat stuttering.
Troubleshooting & Common Fixes
- UI Reset: If your UI is gone after the purge, go to Settings > Setting Archive > Download to restore your cloud backup.
- “Black Screen” on Load: This can happen if the game is interrupted while rebuilding the cache. Delete the
UserCachefolder again and let it rebuild without Alt-Tabbing. - Skills Looking “Boxy”: If effects look like pixels, increase Effect Opacity to 80 and turn off Upscale mode.
Frequently Asked Questions (FAQ)
Does clearing UserCache delete my characters?
No. Your character data, items, and progress are stored on Pearl Abyss servers. UserCache only stores local settings like UI positions and visual effect logs.
Why set Effect Opacity to 70?
At 100%, many class skills (like Wizard or Nova) create so much light that you cannot see enemy “Red/Blue” status bars or ground “Telegraphs.” 70% provides the best tactical clarity.
How often should I clear the cache?
It is recommended to clear your UserCache after every major “Class Reboot” or “New Class” release to ensure the engine isn’t calling old, inefficient shader data.
Conclusion and Expected Results
By cleaning the UserCache and refining the GameOption.txt, you are stripping away the digital “rot” that accumulates in BDO’s local files. You can expect a significant boost in combat fluidity, fewer frame drops during skill combos, and maximum visibility in the middle of a chaotic fight. Los Sueños… wait, wrong game! The world of Black Desert is now optimized for your next grind.
