The DirectX 12 API is required for Ray Tracing. On the "Original" (non-RT) version of RE2, the game could run on DX11 and was rock solid. However, the "Ray Tracing" update forced many systems into DX12 mode. The implementation of RT in RE2 is sensitive; if the ray-tracing acceleration structure builds incorrectly, or if the VRAM fills up due to the extra render target, the Renderdevicedx12.cpp error triggers immediately.
Common triggers include:
Fortunately, this is a well-documented issue with several reliable workarounds. Below is a comprehensive guide to understanding what causes this crash and the definitive steps you can take to fix it. What Causes the Fatal D3D Error?
Resident Evil 2 defaults to DX12 for ray tracing. However, the game is notoriously unstable with DX12 on many cards. The game’s files support DX11, even if the menu hides it. Renderdevicedx12.cpp Fatal D3d Error Resident Evil 2
How to Fix the "renderdevicedx12.cpp" Fatal D3D Error in Resident Evil 2 Remake
Turning off Ray Tracing (RT) often immediately stops the renderdevicedx12.cpp crash.
Resident Evil 2 was one of Capcom's flagship titles utilizing the early iterations of the RE Engine's DX12 implementation. Over time, the community has identified several specific triggers that exacerbate this error: The DirectX 12 API is required for Ray Tracing
Software overlays (like the Steam overlay, Discord overlay, or GeForce Experience overlay) can sometimes hook into the DirectX 12 render process and cause a fatal crash.
The error specifically points to a breakdown in communication between the game engine ( renderdevicedx12.cpp is a source code file handling DX12 rendering) and your graphics hardware. The most common triggers include:
Ensure "Automatically manage paging file size for all drives" is checked, or manually set it to 1.5x your total RAM. Hardware Considerations The implementation of RT in RE2 is sensitive;
The single most common culprit. If your graphics driver has corrupted registry files or lacks optimizations for the RE Engine's ray-tracing updates, it will crash.
In simple terms, this error pops up when the game's graphics system tries to use your graphics card via DirectX 12 and something goes disastrously wrong, causing the game to crash. The full file path in the error message usually looks like this: d:\relauncher\engines\0\gitroot\runtime\modules\render\os\renderdevicedx12.cpp .
