In Sony Vegas - When I render out chroma key with light wrap it triples my render time and drops my processor use to about 18 to 20 %. When I remove light Wrap the processor goes to 100% and cuts my render time by 2/3? As far as I can tell the GPU is not used in any of the render.
So I am wondering what it is about light wrap that has this effect on a render and is there a setting I need to set in Boris????

In order to provide you with the correct answer to your question, I'll need to ask you a question. Have you tried using other BCC filters and if so, do you see the same difference in CPU hit?
Regarding the GPU / CPU thing - most of the filters in BCC are CPU bound and do not use the GPU at all. In BCC 7, you will notice that there is a category of effects that is titled OpenGL ... all of the filters in this group rely totally on the GPU to render a result. There is also a category of filters titled 3D Objects and all of the filters that are in this group rely on the GPU to render. Other than that, they all use the CPU.
