Market Depth Chart and CPU usage

I already tried everything to get MDH working without maxing out CPU usage of one core - no luck. My machine is up-to-date and very capable, Sierra is optimized and running perfectly fast, stable and smooth with all Charts beside the MDH chart on an chart update interval of 250ms. I could even go much lower without any major CPU usage so thats quiet efficient.

But MDH is just taxing CPU to the limit and there seems to be no way for the users to optimize this. Only solution for me is to use a even higher update interval of 500 ms or more to reduce the core usage to around 50% (still too high for my liking) but to have the charts only update twice per second is way to slow.

Attached is a screenshot showing MDH at the RTH close with 250 ms interval. During RTH the usage is not that high as not as much market depth levels are posted but still high..

@ SC Engineers:

Is there any solution for that? Could this MDH study be optimized to be more efficient? Maybe distribute the depth updates to another core?

Second instance or Open GL are not usable for me, already checked that. And I would really love to have MDH working to get rid of Bookmap.

The Market Depth Historical Graph is a very intensive study. Refer to the following for things you can do to improve performance:

When using OpenGL you need to have a very fast GPU with sufficient memory.
