Open the ReShade overlay in-game (typically by pressing the or Pos1 key). Search for the DisplayDepth.fx shader and activate it.
If you are experiencing issues with this version, the most common "fixes" involve configuring the depth buffer correctly, as RTGI requires accurate depth data to calculate lighting.
This guide provides step-by-step solutions to fix this release error and restore path-traced lighting to your games. Why Does the RTGI 01702 Error Happen?
The 0.17.02 iteration of the RTGI shader focused heavily on optimizing the temporal accumulation filters and refining how the shader interacts with the game’s depth buffer. While these changes aimed to reduce the "ghosting" artifacts common in earlier builds, they inadvertently triggered several widespread bugs: rtgi 01702 release fix
Alongside the new lighting algorithm, the June 2025 update revolutionized the reflection system. By implementing (Hierarchical Z-Buffer), the shader can now trace pixel-perfect paths. This creates extremely accurate, crisp reflections without the smearing or blurring artifacts typical of older screen-space solutions.
Fixing issues where the ray tracing would appear "inside out" or disconnected from objects, often resolved by toggling the RESHADE_DEPTH_INPUT_IS_REVERSED preprocessor definition.
A mid-sized bank using an on-premises RTGI-based integration layer experienced the 01702 error during a critical quarterly release. Their initial fix attempts (rebooting servers, re-running the release) failed for six hours. Open the ReShade overlay in-game (typically by pressing
If you are determined to try this "hot" release, ensure you download it directly from Marty's Mods to avoid improper files, and follow the installation steps above to ensure a stable experience. If you'd like, I can:
Ensuring the depth buffer is active by unchecking "Copy depth buffer before clear operations" in ReShade's DX9/DX11/DX12 tab if the effect is invisible. for a specific game?
If you are experiencing the infinite compilation loop, look for the preprocessor definition RT_USE_DYNAMIC_RAYS and ensure its value is explicitly set to 0 instead of letting the compiler guess the loop boundaries. Save the file and restart your game. 3. Correct the Depth Buffer Settings This guide provides step-by-step solutions to fix this
Delete all files related to RTGI (e.g., qquint_rtgi.fx and any associated .fxh files).
RTGI-01702 — Release failure fixed in vX.Y.Z (replace with actual version)
Do delete the entire cache if you need rollback ability. Instead, clear only the validation cache:
The RTGI agent caches previous releases for rollback purposes. When this cache exceeds size limits or becomes corrupted due to disk I/O errors, the release validation step fails with 01702.
Disable Discord, Steam, GeForce Experience, or MSI Afterburner overlays. These frequently hijack the graphics pipeline, forcing ReShade to drop its depth buffer connection.
