GPU PerfStudio2.15 now available for download from http://developer.amd.com/tools-and-sdks/graphics-development/gpu-perfstudio-2/
It has a major fix for DirectX11 games running on Windows 8.1 where it was not possible to connect to some apps from the client. We have removed support for DirectX10 and DirectX10.1 as we are no longer seeing any development activity with this API. The Profiler stability has been improved and support has been added for newer AMD GPUs. We have also fixed an issue with the OpenGL server that was causing blank textures to appear in the client.
