However, the static thresholds perform poorly for Kodi, and the GPU is unable to deliver the video frames on time. Enabling the dynamic, finer thresholds used on all other platforms (including Skylake and Broxton that also have the same multiple powerwell concerns) allows the GPU to pick a more appropriate frequency and not drop frames.
