4D visualization

Hello,
I’m evaluating the library to see if it fits my needs.
I just want to display medical volume data, say 512512512*sizeof(float) = 536MB of float data per frame. I need to display at least at 20fps.
The entire volume cannot fit inside the GPU.
Do you think I can copy fast enough the data from CPU to GPU ?

Can I use the concurrent copy engine (streams) with GVDB ?

Do you have advices on the best strategies ?

thank you

André
