I'm a bit surprised I couldn't find any other posts on the NVidia profiler with MonoGame/Android.
Normally you turn on the profiler by running the adb shell command.
adb shell setprop debug.perfhudes 1
And then you start the app, connect the NVProfiler and walla.
I'm not having much luck connecting the NVPerfHUD to MonoGame and was looking for any tips to connect the profiler.
