Despite years of patches, Borderlands 3 remains picky about system initialization. A common bottleneck involves how the game negotiates dynamic link libraries (DLLs) during boot up. By systematically targeting initialization hooks and ruling out driver conflicts, you can bypass these startup hangs and get back to loot hunting on Pandora without dealing with random desktop crashes.
Understanding the "Event Enable" Process
The event enable process forces Borderlands 3 to execute explicit graphics initialization routines during startup. PC players usually utilize event flags or DLL hook overrides to bypass launch loops, crash-to-desktop errors, or DirectX handshake failures caused by corrupted configuration files, third-party overlays, or driver mismatches.
When you start Borderlands 3, the engine executes a sequence of checks to verify display hardware, sound devices, and anti-cheat components. If a driver or overlay interrupts this pipeline, the process hangs indefinitely. Enabling specific event routines forces the game to skip blocked calls and rely on standard Windows graphics libraries instead. While this functions primarily as a workaround rather than a fundamental engine patch, PC gamers widely rely on it to bypass persistent startup loops.
What Causes the Need for Event Enabling?
Event enabling becomes necessary when background applications, outdated runtime packages, or permission restrictions break the startup sequence. Third-party software—like screen recorders, hardware monitors, or overlay utilities—frequently intercepts graphics calls before the game window initializes, triggering silent crashes.
The Best Event to Enable: dxgi.dll

Enforcing the dxgi.dll event configuration gives players a reliable starting point for clearing startup crashes on Windows PCs. This dynamic link library handles core DirectX 11 graphics infrastructure, and forcing its initialization sequence re-establishes critical handshake calls between the game engine and your graphics card driver.
Because Borderlands 3 defaults to specific DirectX hooks, targeting `dxgi.dll` ensures that the operating system manages memory allocation and display swap chains predictably. This flag forces the game engine to bypass unverified driver features that often cause black screens during launch.
How to Enable the dxgi.dll Event
To enable the `dxgi.dll` event manually, open an elevated Command Prompt by searching for "cmd" in the Windows start menu, right-clicking it, and selecting "Run as administrator." Navigate to your game's binary installation folder using the command line:
cd "C:\Program Files (x86)\Steam\steamapps\common\Borderlands 3\GearShift\Binaries\Win64"
Once inside the directory, execute the debug hook command:
exeinfo.exe dxgi.dll /enable=proddebug
Press Enter, close the terminal window, and launch the game directly through your client.
Alternatives to dxgi.dll: d3d11.dll and d3d9.dll
When standard dxgi.dll tweaks fail, switching to d3d11.dll forces the engine to bypass DirectX 12 entirely, while d3d9.dll acts as a legacy fallback. While DirectX 9 support in modern titles is limited, these secondary hooks help isolate deep graphics pipeline conflicts.
You can apply these alternatives using the exact same elevated command prompt procedure detailed above. Simply substitute `dxgi.dll` in your command line with `d3d11.dll` or `d3d9.dll`. Forced `d3d11.dll` calls work especially well if your system crashes when switching display modes or running dual-monitor setups.
Addressing DirectX Version Conflicts
Borderlands 3 relies heavily on stable DirectX 11 runtime files, though its optional DirectX 12 implementation routinely triggers launch failures on certain hardware setups. Resolving these version conflicts involves resetting your graphics API preferences, installing legacy runtime libraries, and verifying DirectX system integrity using native Windows tools.
DirectX 12 was added to Borderlands 3 to improve CPU utilization, but it frequently causes infinite Claptrap loading screens on startup. If your game crashes before reaching the main menu, forcing the engine back to DirectX 11 usually fixes the problem immediately. You can do this without opening the game by editing your configuration files directly:
- Navigate to
%USERPROFILE%\Documents\My Games\Borderlands 3\Saved\Config\WindowsNoEditor\in Windows File Explorer. - Open
GameUserSettings.iniwith Notepad. - Locate the line reading
PreferredGraphicsAPI=DX12and change it toPreferredGraphicsAPI=DX11. - Save the file and set it to read-only if the game continuously reverts your change.
How to Reinstall DirectX Runtimes
Reinstalling the DirectX End-User Runtime package restores missing or damaged API libraries that modern Windows builds sometimes omit. Running Microsoft’s standalone installer refreshes essential legacy runtime components, ensuring Borderlands 3 accesses every necessary rendering library without throwing missing-file errors upon launch.
Head to Microsoft's official download center and grab the DirectX End-User Runtime Web Installer. Run the package, allow it to overwrite existing libraries, and restart your PC. This process replaces corrupted dynamic libraries without altering your core graphics driver installation.
Understanding DirectX Diagnostic Tool (dxdiag)
Running the DirectX Diagnostic Tool allows you to inspect system-level graphics drivers, direct acceleration features, and logged display errors. Accessing dxdiag gives a clear breakdown of active driver versions and hardware feature levels, making it simple to catch corrupted system components before troubleshooting further.
Press Windows Key + R, type dxdiag, and hit Enter. Check the "Display" tabs to confirm that Direct3D Acceleration is listed as "Enabled." Peruse the "Notes" section at the bottom of each tab to quickly spot flagged driver conflicts or broken system components.
Graphics Driver Updates & Compatibility
Outdated or improperly installed display drivers rank among the top reasons for Borderlands 3 failing to load past the splash screen. Updating your Nvidia, AMD, or Intel display drivers resolves day-one profile bugs, while rolling back recent driver updates helps bypass unexpected regressions introduced by newer software builds.
Graphics driver updates pack essential performance fixes and game-specific profiles. However, corrupt driver installations are just as troublesome as outdated ones. Performing clean driver installations ensures that leftover registry keys from old hardware don't interfere with game execution.
Where to Download Graphics Drivers
Downloading fresh driver packages directly from hardware manufacturers ensures you receive fully signed software built for your specific GPU architecture. Official driver suites from Nvidia, AMD, and Intel pack dedicated profiles for Borderlands 3 that address known memory leaks and shader compilation hitches.
- Nvidia Graphics Cards: Grab drivers directly via GeForce Experience or Nvidia's official driver search page.
- AMD Radeon Cards: Download Adrenalin Software updates through AMD's driver support portal.
- Intel Graphics: Use the Intel Driver & Support Assistant to find verified Arc or integrated drivers.
Dealing with Driver Conflicts
Reverting to a previous display driver version fixes launch crashes that suddenly appear following a driver update. Windows Device Manager and vendor utility suites allow you to perform clean rollbacks, stripping out broken profile settings while preserving core system stability across your game library.
If updating drivers breaks stability, use Display Driver Uninstaller (DDU) in Windows Safe Mode to completely wipe existing GPU drivers. Once rebooted, perform a clean installation of a known, stable driver release to rule out lingering configuration bugs.
Verifying Game File Integrity
Verifying game file integrity compares your local Borderlands 3 installation against official store manifest files to detect missing or corrupted game assets. Both Steam and the Epic Games Launcher include built-in validation utilities that automatically re-download damaged executables, scripts, and asset bundles without wiping save data.
Storage drives occasionally suffer silent corruption during large game patches or sudden power outages. Validating game files ensures every binary executable matches its original hash signature, restoring broken initialization routines in a few clicks.
How to Verify File Integrity in Steam
Steam validates game installations through its built-in properties menu, cross-checking hash signatures for every file on your drive. Right-clicking Borderlands 3, opening its local files menu, and initiating a validation check prompts Steam to replace corrupted game scripts within minutes.
- Open your Steam Library and right-click Borderlands 3.
- Select Properties, then click the Installed Files tab.
- Click Verify integrity of game files and allow the scan to complete.
How to Verify File Integrity in Epic Games Store
The Epic Games Launcher offers a direct repair feature within your library management menu. Selecting the three dots next to Borderlands 3 and running the verify command scans your installation directory, identifying corrupted assets and quietly queuing fresh replacements in your download manager.
- Open the Epic Games Launcher and select your Library.

Advanced Troubleshooting: Clean Install and System Scan
Performing a clean game reinstallation combined with a system file check removes lingering configuration clutter and eliminates background system errors. This thorough reset cleans out broken user settings folders, clears cached shader files, and fixes system file corruptions that prevent the game engine from opening.
If basic file verification and driver updates fall short, system-level issues are likely preventing the game from launching. Corrupted Windows system files, overly aggressive antivirus software, or permission issues in your user profile can prevent the game process from loading into RAM.
Performing a Clean Install
A clean reinstall requires removing Borderlands 3 through your client, then manually deleting left-behind save and configuration folders before downloading fresh game files. Clearing out remaining directories under your Documents folder guarantees that old, broken startup parameters do not persist into the fresh installation.
After uninstalling through Steam or Epic, delete the leftover Borderlands 3 folders found in both your installation directory and %USERPROFILE%\Documents\My Games\. Back up your save files (located in the Saved\SaveGames folder) before deleting anything to keep your character progression intact.
Running a System Scan
Running system scans via System File Checker (sfc /scannow) repairs damaged Windows OS files that cause application initialization failures. Combined with full malware scans, this process verifies that core dynamic link libraries across your operating system function properly without external interference.
