System Analyzer can simulate the application performance with various CPU settings.
To determine whether your application performance is CPU-bound, do the following:
- Verify that your application is not VSync-bound. Vsync is enabled if you see the gray highlight in the System Analyzer Notification pane.
- If Vsync is disabled, proceed to step 2.
- If the VSync is enabled, review the frame rate in the top-right corner of the System Analyzer window. If the frame rate is around 60 FPS, your application is VSync-bound. Otherwise, proceed to step 2.
- Force a different CPU frequency using the sliders in the Platform Settings pane of the System Analyzer window. If the FPS value changes when you modify the CPU frequency, the application is likely to be CPU-bound.
If your application is not CPU-bound, proceed to the individual frame analysis with Graphics Frame Analyzer to identify possible performance improvements within the GPU.
