Complete Guide: Running Borderlands 3 Twice on One PC

Running Borderlands 3 simultaneously on a single computer (known as “dual-instancing”) has become increasingly popular among players who want to:

  • Farm loot more efficiently by controlling two characters at once
  • Test different build combinations without switching characters
  • Play co-op with themselves to experience multiplayer mechanics solo
  • Create content showing multiple perspectives simultaneously

Technical Requirements for Dual-Instancing

The practice places significant demands on your hardware. Here’s what you need to consider:

1. CPU Requirements

Borderlands 3 is moderately CPU-intensive, with the game primarily utilizing 4-6 cores. When running two instances:

  • Minimum: 6-core/12-thread CPU (e.g., Intel i5-12400, AMD Ryzen 5 5600)
  • Recommended: 8-core/16-thread CPU (e.g., Intel i7-12700K, AMD Ryzen 7 5800X3D)
  • Optimal: 12+ core CPU (e.g., Intel i9-13900K, AMD Ryzen 9 7950X)
CPU Model Single Instance FPS (1080p Ultra) Dual Instance FPS (Estimated) Performance Drop
Intel i5-12400 90-110 40-50 ~55%
AMD Ryzen 7 5800X3D 100-120 50-60 ~50%
Intel i9-13900K 120-140 65-75 ~45%

2. GPU Requirements

The graphics card bears the brunt of the workload when dual-instancing. VRAM becomes particularly critical:

  • Minimum: 8GB VRAM (e.g., RTX 3060, RX 6700 XT)
  • Recommended: 12GB+ VRAM (e.g., RTX 3080, RX 6800 XT)
  • Optimal: 16GB+ VRAM (e.g., RTX 4090)

At 1080p with medium settings, each Borderlands 3 instance uses approximately 4-5GB VRAM. At 4K ultra, this jumps to 7-9GB per instance.

3. RAM Requirements

Borderlands 3 typically uses 8-12GB RAM per instance. With two instances plus system overhead:

  • Minimum: 16GB (tight, may cause stuttering)
  • Recommended: 32GB
  • Optimal: 64GB (for future-proofing)

4. Storage Considerations

While not as critical as other components, having Borderlands 3 installed on an SSD is highly recommended when dual-instancing to:

  • Reduce loading times between instances
  • Minimize stuttering during asset streaming
  • Improve overall system responsiveness

Plan for approximately 100GB of storage space (the game plus two sets of shader caches).

Step-by-Step Guide to Dual-Instancing Borderlands 3

  1. Verify Hardware Compatibility

    Use our calculator above to estimate whether your system can handle dual-instancing. Pay particular attention to:

    • CPU core/thread count
    • GPU VRAM capacity
    • Total system RAM
  2. Prepare Your System

    Before attempting to run two instances:

    • Update all drivers (especially GPU drivers)
    • Close all background applications
    • Disable unnecessary startup programs
    • Set power plan to “High Performance” in Windows
    • Ensure adequate cooling (dual-instancing increases thermal load)
  3. Launch the First Instance

    Start Borderlands 3 normally through:

    • Epic Games Launcher, or
    • Steam (add “-noeac -nolauncher” to launch options for better compatibility)

    Log in to your first character and get to a safe area (e.g., Sanctuary).

  4. Launch the Second Instance

    Method 1: Using Steam

    1. Right-click Borderlands 3 in Steam → Properties
    2. In Launch Options, add: -noeac -nolauncher -secondary
    3. Close the game if running, then launch again
    4. Steam will ask if you want to launch another instance – confirm

    Method 2: Using Epic Games Launcher

    1. Navigate to your Borderlands 3 installation folder
    2. Find OakGame.exe (typically in Binaries\Win64)
    3. Create a shortcut to this executable
    4. Right-click shortcut → Properties → Add -noeac -nolauncher to the target
    5. Launch the shortcut while the first instance is running
  5. Configure In-Game Settings

    For each instance, adjust these settings to optimize performance:

    • Set resolution to match your monitor(s)
    • Enable DLSS/FSR if available (Quality or Balanced mode)
    • Reduce or disable:
      • Volumetric Fog Resolution
      • Screen Space Reflections
      • Depth of Field
      • Motion Blur
    • Cap FPS to 60 if experiencing instability
  6. Manage System Resources

    To prevent one instance from starving the other:

    • Open Task Manager (Ctrl+Shift+Esc)
    • Find both Borderlands 3 processes
    • Right-click → Set priority:
      • First instance: “High”
      • Second instance: “Above Normal”
    • Set affinity to distribute cores evenly if needed
  7. Monitor Performance

    Use these tools to track system performance:

    • MSI Afterburner + RivaTuner (for FPS and GPU stats)
    • HWMonitor (for CPU/GPU temps and usage)
    • Process Explorer (for detailed process analysis)

    Watch for:

    • GPU VRAM usage approaching capacity
    • CPU usage consistently at 100%
    • Temperatures exceeding 85°C (CPU) or 80°C (GPU)

  • Try borderless windowed mode if using multiple monitors

Advanced Techniques for Power Users

1. Virtual Machine Approach

For systems with very high core counts (16+), you can:

  1. Create a lightweight Windows VM using Hyper-V or VMware
  2. Assign dedicated CPU cores and GPU resources (using GPU passthrough)
  3. Install Borderlands 3 in the VM
  4. Run one instance natively and one in the VM

Pros: Better isolation, can assign specific resources

Cons: Complex setup, some performance overhead

2. Custom Batch Scripts

Create a batch file to launch both instances with specific parameters:

@echo off
start "" "C:\Epic Games\Borderlands3\OakGame\Binaries\Win64\OakGame-Win64-Shipping.exe" -noeac -nolauncher
timeout /t 10
start "" "C:\Epic Games\Borderlands3\OakGame\Binaries\Win64\OakGame-Win64-Shipping.exe" -noeac -nolauncher -secondary

3. Affinity Masking

Manually assign CPU cores to each instance:

  1. Launch both instances
  2. Open Task Manager → Details tab
  3. Right-click each Borderlands 3 process → Set affinity
  4. Assign first 6 cores to first instance, next 6 to second instance

4. RAM Disk for Shader Cache

For systems with abundant RAM:

  1. Create a RAM disk (using software like ImDisk)
  2. Move the Borderlands 3 shader cache to the RAM disk
  3. Symlink the original location to the RAM disk

This can reduce stuttering during shader compilation.

Legal and Ethical Considerations

Before attempting to run two instances of Borderlands 3, consider these important factors:

1. End User License Agreement (EULA)

Gearbox Software’s EULA typically prohibits:

  • Running multiple instances for farming purposes
  • Automating gameplay across multiple instances
  • Exploiting multi-instancing for unfair advantages

While running two instances for legitimate purposes (e.g., content creation) is generally tolerated, abusive practices may result in account restrictions.

2. Anti-Cheat Considerations

Borderlands 3 uses Easy Anti-Cheat (EAC). Running multiple instances:

  • May trigger false positives in anti-cheat systems
  • Could be interpreted as attempting to bypass protections
  • Might cause temporary bans if the system detects unusual behavior

The -noeac launch parameter disables EAC, but:

  • You won’t be able to play online
  • Some features may be disabled
  • Use at your own risk

3. Fair Play Guidelines

If using dual-instancing for farming:

  • Don’t use it to dominate leaderboards
  • Avoid trading items between your own accounts
  • Don’t use it in competitive modes
  • Be prepared for potential consequences if reported
