What does the GPU Mem indicator mean in the vMix status bar?

Since version 22, vMix now includes a special "GPU Mem" indicator.
This is a value from 0 to 100% and refers to a small amount of cache memory vMix uses to transfer video data from the source to the graphics card.
(For example from a Capture Card to the GPU)
 
N.B: This cache memory is a fixed size on NVIDIA cards and is much smaller than the amount of total GPU memory available.
 
The more inputs you have that require real time video transfer, the higher the percentage.
100% means you will start to see performance issues such as high render times and as a result, dropped frames or video stutters.
 

Inputs that impact GPU Mem

These inputs in particular will increase the percentage, reducing the number of these types of inputs will improve performance.
 
Title (Old titles only, the new GT titles are fully GPU accelerated and therefore do not need to transfer video data)
Video (List uses far less memory, so grouping Video Inputs into a single List is recommended)

Camera
NDI
Flash
