We are using the Nvidia NVS 810 right now on a large projection installation. Composition is approx. 2500x2500 pixels, content is roughly the same size rendered in DXV3 with simple playback. Output is 5 slices to 5 1920x1080 outputs. Lots of edge blending going on too.
Running with Advanced Output Disabled: 40-50fps
We've added another layer with a small movie showing titles above the main show layer, this drops frame rates to:
24-34fps which is still acceptable but damn close stuttering. Our CPU is getting taxed at 70% usage (1151 socket 350 i5)
Looking into getting this to run faster.
- Render all clips with title graphic so we don't have to use another layer.
Scale all clips to match exact size of composition (some are close but are scaled up causing processing).
Render all clips with any effects added (some needed Saturation or Exposure to make them pop)
Check RAM Speed, maybe consider increasing.
Try overclocking CPU or consider a faster unit.
