The biggest fear with moving to DX11 is losing visual quality. Let's address the trade-offs.
Switch to the new DirectX 11 mode if:
Stick with DirectX 12 if:
As graphics APIs evolve, older games risk being left behind. Microsoft is pushing DirectX 12 Ultimate and the upcoming DirectX 13. However, the Resident Evil 3 modding community has embraced DX11 as the preservation standard. New mods—including randomizers, HD texture packs, and even the "Infernal Nemesis" AI overhaul—are now being developed and tested primarily on DX11 for maximum compatibility.
By adopting this new DX11 wave, you are ensuring that Resident Evil 3 will run smoothly on future hardware (like Intel's Battlemage GPUs or AMD's Strix Point APUs) that may have quirky legacy DX12 drivers. resident evil 3 directx 11 new
Instead of relying on Screen Space Ambient Occlusion (SSAO), which cannot see objects off-screen or behind the camera, we use a simplified Ray Marching approach within the depth buffer, combined with a temporal accumulation for stability.
Step A: World Position Reconstruction Reconstruct the world position of every pixel from the depth buffer using the inverse View-Projection matrix.
// Standard DX11 depth reconstruction
float4 positionCS = float4(TexCoord.x * 2.0 - 1.0, TexCoord.y * 2.0 - 1.0, depth, 1.0);
float4 positionWS = mul(InvViewProj, positionCS);
positionWS.xyz /= positionWS.w;
Step B: Ray Generation For every pixel, cast 4-8 low-noise rays in a hemisphere oriented around the pixel's normal vector.
Step C: The "Volatile" Check This is the "New" logic. Instead of full ray-tracing which is heavy, we check for "Volatile" interactions: The biggest fear with moving to DX11 is

The "new" DirectX 11 (DX11) piece for Resident Evil 3 refers to the official "dx11_non-rt" beta branch on Steam
. Capcom re-released this version following community feedback after a mandatory update pushed the game to DirectX 12 (DX12) with ray tracing, which increased system requirements and broke compatibility for many mods. How to Access the DirectX 11 Version You can switch to the DX11 version via the Steam library using these steps: Right-click Resident Evil 3 in your Steam Library and select Properties Navigate to the tab on the left. In the "Beta Participation" dropdown, select dx11_non-rt Stick with DirectX 12 if: As graphics APIs
Close the menu; Steam will automatically download a small update to revert the game files. Key Benefits of the DX11 "Piece"
The most common complaint among PC players who default to DX12 is micro-stutter. This manifests as a brief, jarring freeze when:
This is typically caused by shader compilation stutter. In DX12, the responsibility for managing memory and compiling shaders is shifted from the driver to the developer. If the game hasn’t pre-cached every shader permutation (and RE3 hasn’t), the CPU grinds to a halt mid-explosion to compile them on the fly.
DirectX 11 handles this differently. The driver does the heavy lifting, often resulting in smoother frame times during new asset streaming. While you might lose 5-10% peak FPS in DX11 versus DX12, the consistency is night and day. There are no random hitches—just a flat, predictable performance curve.
