How can I detect if PIX is running?

Question

My application adapts to a slow framerate in a few different ways. When I run a PIX experiment, rendering gets much slower so these techniques get activated. I would like to disable this without having to do a seperate build when I want to use PIX. Something like:

if (running_slow() && !running_pix()) {
    reduce_graphics();
}

In the DirectX June 2010 SDK:

bool running_pix() {
    return D3DPERF_GetStatus() != 0;
}
