AMD has announced a new addition to their Radeon Developer Suite family called Driver Experiments. With, Driver Experiments, AMD wants game and graphic developers to test their applications and observe if they crash or work incorrectly on an AMD GPU.
Like all the tools in the Radeon Developer Suite, Driver Experiments are intended for developers, not end users. While you might come across features like V-sync control and settings in AMD software, Driver Experiments are not meant to tweak the gaming experience. Instead, they can influence an application’s behavior, performance, or even stability.

Access driver settings previously only available to AMD engineers
Driver Experiments allows developers to control the low-level behavior of the graphics drivers, offering a way to change the behavior and performance characteristics of a game or other graphics application without modifying its source code or configuration.
Additionally, Driver Experiments give you access to features that were previously only available to AMD engineers working on driver development. For instance, you can disable support for ray tracing to observe performance changes or some optimizations in the shader compiler. Here’s a rundown of all the options included with Driver Experiments:
Experiments/technologies
• Disable mesh shader support
• Disable sampler feedback support
• Disable raytracing support
• Disable variable rate shading
• Disable GPU work graphs support
• Disable low-precision support
• Disable native 16-bit type support
• Disable AMD vendor extensions
• Disable compute queue support
• Disable copy queue supportOptimizations
• Disable floating-point optimizations
• Disable shader compiler optimizations
• Disable barrier optimizations
• Disable acceleration structure optimizations
• Force shader wave size
• Disable raytracing shader inlining
• Disable shader cacheSafety features
• Disable depth-stencil texture compression
• Zero unbound descriptors
• Thread-safe command buffer allocator
• Force structured buffers as raw
• Vertical synchronization
Driver Experiments can help identify bugs in graphics applications
Driver Experiments can also come in handy for debugging issues in graphics applications. With the help of other tools, like Radeon GPU Detective (RGD), Radeon GPU Profiler (RGP), Radeon Memory Visualizer (RMV), or Radeon Raytracing Analyzer (RRA), Driver Experiments can help you identify bugs that often arise from incorrect use of the graphics API (DirectX 12, Vulkan).
Currently, Driver Experiments are only compatible with Radeon RX 5000, 6000, and 7000 series GPUs and can be activated using the Radeon Developer Panel. The new tool is supported on both Windows 10 and 11 and requires the latest Adrenaline 24.9.1 driver update.
