Red Dead Redemption 2 crashing on PC? ERR_GFX_STATE, “exited unexpectedly”, FFFFFFFF and Error Code 18: Rockstar’s official fixes (November 2026)

Red Dead Redemption 2 crashes on launch on your PC, shows ERR_GFX_STATE, “Red Dead Redemption 2 exited unexpectedly”, Unknown error FFFFFFFF or “Rockstar Games failed to initialize graphics device. Error Code: 18”? Here are the fixes published by Rockstar Games Customer Support, grouped by error, as read on November 11, 2026. TricknFix did not test these steps itself: they are Rockstar’s instructions, not a guarantee.

1. Update your graphics driver first

• For both ERR_GFX_STATE and “exited unexpectedly”, Rockstar says out-of-date graphics drivers are the most common cause. Install the latest driver from NVIDIA, AMD or Intel.

2. ERR_GFX_STATE: switch from Vulkan to DirectX 12

• From the Main Menu, open Settings, Graphics, set Advanced Settings to Unlocked, then choose DirectX 12 under Graphics API. Save, but do not restart when prompted: go back to the Main Menu, exit the game, then launch it again.

3. Run RDR2.exe as administrator and disable fullscreen optimization

• Rockstar Games Launcher: Settings, Red Dead Redemption 2 under My Installed Games, Open under View installation folder.
• Steam: Library, right-click the game, Properties, Local Files, Browse.
• Epic Games Launcher: Library, three dots on the game tile, Manage, folder icon on the Installation tab.
• Then right-click RDR2.exe, Properties, Compatibility tab: check “Run this program as an administrator” and disable fullscreen optimization, click OK and launch the game from the same launcher.

4. Unknown error FFFFFFFF

• Rockstar says it can come from external audio devices, out-of-date drivers or a misconfigured Advanced Graphics setting. Plug your headset or speakers in only after the game has started.
• You can also switch the API outside the game: in Documents\Rockstar Games\Red Dead Redemption 2\Settings, open system.xml in Notepad, change kSettingAPI_Vulkan to kSettingAPI_DX12, save, delete the files starting with “sga_” in the same folder, then launch the game.

5. Error Code 18 (“failed to initialize graphics device”)

• Rockstar says this error comes from the Graphics API setting. Close the game, apply the same change (Vulkan to DX12) in the settings file in Documents\Rockstar Games\Red Dead Redemption 2, save, then restart the game.
