How Do You Fix Tekken 8 DX12 or D3D12 Command Line Argument Errors? Proven Solutions for Gamers

Struggling with Tekken 8’s D3D12 Issue? Here’s How to Fix It Quickly

Are you facing the dreaded DX12 not supported or -d3d12 command line error in Tekken 8? Don’t worry—this guide will walk you through step-by-step solutions to resolve DirectX 12 issues and get the game running smoothly, even if your system doesn’t fully support DX12. Let’s dive in.

Why Does the Error Happen?

The error occurs because Tekken 8 requires DirectX 12 (DX12) to run. If your system lacks DX12 support or your GPU (graphics card) isn’t compatible, the game won’t launch properly. Additionally, outdated drivers or unsupported operating systems can also cause this issue.

Solutions to Fix Tekken 8 DX12 or D3D12 Errors

Follow these steps to troubleshoot and fix the problem:

Solution1: Check Your System’s DirectX Version

1. Press Windows + R to open the Run dialog box.
2. Type dxdiag and hit Enter.
3. In the DirectX Diagnostic Tool, click the Display tab.
4. Look for “Feature Levels” on the right-hand side. If you see 12_0 or higher, your GPU supports DX12. If not, your hardware cannot run DX12.

Solution 2: Update Your Operating System

If you’re using Windows 7 or 8, upgrade to Windows 10 or later. Older OS versions don’t support DirectX 12.

Go to Settings > Update & Security > Windows Update and install any pending updates.

Solution 3: Update Your Graphics Drivers

Outdated GPU drivers can cause DX12 errors. Here’s how to update them:

For NVIDIA users:

1. Download and install the GeForce Experience app from NVIDIA’s website.
2. Open it, go to the Drivers tab, and click Download for the latest driver.

For AMD users:

1. Visit AMD’s official website and download their Adrenalin Software.
2. Use it to update your GPU driver.

Solution 4: Remove DX12 Command Line Arguments

If Tekken 8 is set to force DX12 via Steam launch options:

1. Open Steam and navigate to your game library.
2. Right-click on Tekken 8 and select Properties.
3. Under the Launch Options, remove any -dx12 or -d3d12 arguments.

Solution 5: Repair Corrupted System Files

Corrupted Windows files can interfere with DirectX functionality. To fix this:

1. Type cmd in the Windows search bar.
2. Right-click on Command Prompt and select Run as Administrator.
3. Enter the following command: sfc /scannow
4. Wait for the scan to complete (this may take a few minutes).
5. Restart your PC and try launching Tekken 8 again.

Solution 6: Force DirectX 11 Mode

If your system doesn’t support DX12, you can force the game to run in DirectX 11 (DX11):

1. Open Steam, right-click on Tekken 8, and go to Properties.
2. In the Launch Options box, type: -dx11

This will make Tekken 8 use DX11 instead of DX12. Note that this may reduce performance or cause minor graphical issues.

Solution 7: Roll Back Graphics Drivers

If updating your GPU driver caused new problems:

1. Press Windows + X and select Device Manager.
2. Expand the Display Adapters section.
3. Right-click on your GPU and choose Properties.
4. Go to the Driver tab and click Roll Back Driver (if available).
5. Restart your PC after rolling back.

Additional Tips

• Ensure your system meets Tekken 8’s minimum requirements.
• Close unnecessary background apps before launching the game.
• Verify game files in Steam by right-clicking on Tekken 8 > Properties > Local Files > Verify Integrity of Game Files.

By following these steps, you should be able to resolve most DirectX-related issues in Tekken 8. Good luck, and enjoy getting back into the fight!
