Hi Tom.

As I recall, this allows Vmix to use higher GB video cards more efficiently -or increase the cache being used - especially with regards to a high number of inputs. I believe the way that Martin phrased it that it increases the efficiency of the cache within the GPU.

Martin:
"With productions using a large number of inputs, it is possible to exceed the memory limits of the internal "cache"
the graphics card uses to transfer this data to the GPU. When this occurs, you will see high render times without correspondingly
high usage on the GPU or CPU."
