baldurk Handle D3D12 register spaces with high values without full array size
* Technically register space values are arbitrary so the array should not be
  resized to account for all space indices, in case one is very large.

There are binary releases available, built from the release targets. If you just want to use the program and you ended up here, this is what you want :).

It's recommended that if you're new you start with the stable builds. Nightly builds are available every day from master branch here if you need it, but correspondingly may be less stable.


The text documentation is available online for the latest stable version, as well as in renderdoc.chm in any build. It's built from restructured text with sphinx.

As mentioned above there are some youtube videos showing the use of some basic features and an introduction/overview.

There is also a great presentation by @Icetigris which goes into some details of how RenderDoc can be used in real world situations: slides are up here.


RenderDoc is released under the MIT license, see for full text as well as 3rd party library acknowledgements.


Building RenderDoc is fairly straight forward on most platforms. See for more details.
