How do the Intel® GPA System Analyzer HUD and Intel® GPA Frame Analyzer help identify optimization opportunities in my game?
The Intel® GPA System Analyzer HUD application provides access to system-wide metrics for your game, including CPU, GPU, Microsoft DirectX*, and the graphics driver. Within the Intel GPA System Analyzer HUD you perform various “what-if” experiments to diagnose at a high level where your game’s performance bottlenecks are concentrated. If the Intel GPA System Analyzer HUD shows your game to be CPU-bound, perform additional fine-tuning of your application using one of the other Intel performance optimization products such as Intel® Parallel Studio or Intel® VTuneTM Amplifier XE Performance Profiler. If the performance bottlenecks are found to be within the GPU, the Intel® GPA Frame Analyzer allows you to drill down within a single graphics frame to pinpoint specific rendering problems, such as texture bandwidth, pixel shader performance, level-of-detail issues, or other bottlenecks within each portion of the rendering pipeline. For example, using the “simple pixel shader” you can determi
