Can you confirm that RPSWREQ and CAGF are 1050MHz after doing so?
If you get really bored, try
<a href="http://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=pmu">http://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=pmu</a>, SNA and
intel-gpu-overlay (from <a href="http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/">http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/</a>).
That should give a graph of what is going on with render requests, CPU and GPU
frequencies.</pre>
