--- Comment #10 from Greg Sutcliffe <bugsfreedesktop at emeraldreverie.org> ---
I've just noticed slightly different behaviour in the gpu overlay for the game
I'm really interested in fixing (Path of Exile, which is mostly rendered on the
nVidia card and shipped to the Intel display via the Primus VirtualGL layer).

In this case, the gpufreq always remains constant, around 650Mhz, even when the
frame rate is fine. It's the power consumption that changes when the fps drops
- it's typically idling around 600mW, but during an fps drop, the power
consumption drops to 200mW. No idea how to interpret that, but it seemed like
relevant data, so there it is.
