I created some basic DOP Network content in Houdini 20.5 and in Houdini 21.0 but I never saw any simulation into the viewer. I changed the 3D Viewer to Vulkan and to OpenCL (in Houdini 20.5) but when I enter into the Dynamics context of the DOP Network I only see the geometries but no movement or simulation.
I see the blue line into the timeline, I have the flag display (the blue one) on the dopnet node but nothing. I tried with simple particles setup, with a RBD simple with gravity force but I don't see any movemente into the viewer.


I don't know if it had to be related with the system requirements or not. My laptop is old and it has a graphic device NVIDIA Geforce GTX 1070 with 8GB o VRAM. I have updated the latest driver for the graphic, and into the System Requirement. I read the minimum requirement for Hou 20.5 and Hou 21.0 and it looks like my computer matches with the minimun requirement although it is old.
