GPU Reshape




Brought to you by Miguel Petersen, Avalanche Studios Group, and AMD.

Meet GPU Reshape, a powerful tool that leverages on-the-fly instrumentation of GPU operations with instruction level validation of potentially undefined behavior.

Standalone desktop application, no integration required.

Download now - v0.9.0 Beta

This release includes the following features:

  • Resource Bounds
    Validation of resource read / write coordinates against its bounds.
  • Export Stability
    Numeric stability validation of floating point exports (UAV writes, render targets, vertex exports), e.g. NaN / Inf.
  • Descriptor Validation
    Validation of descriptors, potentially dynamically indexed. This includes undefined, mismatched (compile-time to runtime), out of bounds descriptor indexing, and missing table bindings.
  • Concurrency Validation
    Validation of resource concurrency, i.e. single-producer or multiple-consumer, between queues and events.
  • Resource Initialization
    Validation of resource initialization, ensures any read was preceded by a write.
  • Infinite Loops
    Detection of infinite loops. Experimental.

Additionally, certain features, such as descriptor validation and loops, can safeguard a potentially erroneous operation, preventing undefined behaviour during instrumentation. This is especially useful if the error would result in a GPU crash, limiting the application’s ability to write out useful debug information of the issue.


Instrument and validate your applications, track down issues to the exact line of source code, and determine exactly what went wrong.

Out of the box usage requires no integration, and can be done in just a few clicks, all at interactive frame rates.

GPU Reshape supports both DirectX® 12 and Vulkan®.


Attach to running applications, potentially across network boundaries, to start instrumenting your applications.

Applications may also be launched from the toolset with the desired feature set.


Instrument entire applications in just a few clicks.

Instrumentation may be changed on the fly, and can be specialized on a per-shader and pipeline basis. Customize your workspace as needed.


Investigate validation errors on the exact line of source code, with, for example, the resource and coordinates accessed.

GPU Reshape is agnostic to the front-end language, such as HLSL or GLSL, as it functions solely on the instructions and associated symbols.
