To determine a proper average RAM / VRAM (main memory, GPU memory) consumption, it is necessary to load several representative models (small, medium, large) into the 3DViewStation WebViewer or Desktop and note the corresponding average values.

Evaluating RAM / VRAM consumption using the Process Explorer:

▪Download the Process Explorer software (https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer)

▪Load the 3DVS test file(s) into the 3DViewStation WebViewer or Desktop

▪Open the Process Explorer

▪Locate CRendererInstance.exe (or 3DViewStation.exe) in the Process Explorer Process list

▪Right-click on CRendererInstance.exe (or 3DViewStation.exe) and select Properties... from the context menu

▪Select the Performance tab and get the value of Virtual Memory > Private Bytes

▪Select the GPU Graph tab and get the value of Dedicated GPU Memory

Example, with 20 parallel sessions:

▪The test file is approximately 65 MB (as 3DVS) on hard drive.

▪Consumed RAM is 625 MB (Private Bytes)

▪Consumed VRAM is 307 MB (Dedicated GPU Memory)

Multiplied with 20 concurrent sessions:

▪RAM: 625 MB × 20 = 12.500 MB à 16 GB

▪VRAM: 307 MB × 20 = 6.140 MB à 8 GB

Assuming a maximum of 20 parallel sessions, a server with at least 16 GB of RAM and a graphics card with at least 8 GB of VRAM is sufficient.

Load sharing between multiple servers or servers with multiple graphics cards is possible.
