GPU PERFSTUDIO 2 – THE TOOLS

 Frame Debugger – Select a draw call – View all game resources/state bound to the pipeline  Frame Profiler – Identify costly draw calls – Identify GPU bottlenecks, investigate at the counter level  Shader Debugger/Editor – Edit & Debug HLSL and Assembly code from inside an app – Step, breakpoints, inspect register values.

 API Trace Viewer – Inspect all API calls (with arguments) – Visualize multi-threaded API usage – CPU timeline information for each API call
