Troubleshooting

Try these when DttR starts but crashes, renders incorrectly, or behaves differently than expected.

Game crashes on startup

First, try a different Graphics API. Open dttr-config.exe, go to Graphics, and change Graphics API from auto to one of these:

  • vulkan
  • direct3d12
  • opengl

Save, close the config tool, then start DttR again. If one backend crashes or shows a blank window, another one may still work on the same machine.

If DttR still crashes:

  • Turn off fullscreen and start in a window.
  • Set MSAA Samples to 1.
  • If you are using the Modding build, temporarily disable third-party mods or remove them from the mods directory.

Game crashes during intro movies

If DttR launches but crashes during the opening videos or before the main menu, try skipping the intro movies.

Open dttr-config.exe, enable Skip Intro Movies, save, then restart DttR.

If this fixes the crash, mention that in any bug report.

Graphics are missing, flickering, or otherwise broken

Try switching between Graphics API backends first. If the problem changes between backends, mention that in the bug report; renderer bugs are often backend-specific.

If only polygon movement or seams look wrong, try switching Vertex Precision between native and subpixel.

If that does not work, try these next:

  • Setting Scaling Method back to logical.
  • Setting Scaling Fit to letterbox.
  • Turning Sprite Smooth off and/or setting MSAA Samples to 1.

After each config change, save and restart the game.

Controller input is wrong or missing

Open dttr-config.exe, turn on Enable Gamepad, save, then restart DttR with the controller already connected.

If DttR listens to the wrong controller, try changing Gamepad Index. If a stick drifts or feels unresponsive, adjust the matching deadzone field in small steps.

Audio is distorted or too loud

Open dttr-config.exe and lower MSS Sample Gain. Very high gain values can clip and sound distorted.

Still having issues?

If you are still having problems, report the issue through DttR's GitLab repository.

Include:

  • The DttR version you are using.
  • Whether you downloaded Vanilla or Modding.
  • Your selected Graphics API.
  • Your game source: CD, installed copy, or ISO.
  • dttr.log, with Log Level set to debug or trace.
  • If requested, the relevant crash .dmp files created by DttR. Crash dumps may contain sensitive information, so do not post them publicly unless asked.
