If you're developing new effects, debugging with RenderDoc is insanely useful. It looks more intimidating than it is:
It's freeware and you can download the windows version from https://renderdoc.org/builds
After installation, ...
- exit T3.exe, if it's running
- in your IDE (Rider or Visual Studio) use Build → Build Solution
- start RenderDoc
- find the "Launch Application" tab
- setup the Executable Path and Working directory. For me this looks like:

Press F12 to capture a frame. Then find and select the tab called "t3 [PID 12334]" and double click the screenshot of the frame capture:
Select the "Texture Viewer" Tab and then explore the render steps on the left:
The Pipeline state will the give you a detailed overview of what PRECISELY the graphics card did for this frame:
- You can analyze and download(!) all textures
- See and debug all shaders
- Check if an effect was called with the parameters you expected
- Check and analyze and download all relevant structure buffers
