I’m trying to get draw call timings through Tegra Graphics Debugger on a Google Project Tango tablet. Everything seems to work fine but the GPU time for all draw calls is always 0.
I have done the following:
- Built against libNvidia_gfx_debugger_stub.a instead of EGL and GLESv3.
- Included libNvidia_gfx_debugger.so and libNvPmApi.Core.so in the APK.
adb shell setprop debug.perfhudes 1.
Is there something more I need to do to get GPU timings?
I’ve downloaded and installed Tegra Graphics Debugger 2.2 although the Help > About reports version 2.1.
