<pre>This issue will be investigated by the VPG team. We are able to bring the
performance back as previously seen before the GuC by forcing the GPU to run at
a lower frequency (i.e., 300MHz). So far the analysis of the investigation
points to an imbalance of the GPU/CPU frequencies when the GuC submission is
enabled causing the GPU frequencies to run too high. On certain test loads the
lower CPU frequency may be causing the drop in fps.</pre>
