Low FPS when subscribing to point cloud topic. #227
Comments
I need more information to help you:
One of the main cause maybe running Rviz on the same machine.
To verify that is Rviz that slows down the system you can check the pointcloud generation frequency with this test:

Thanks for the response. This is running with GPU (nvidia 1060) and CPU ( Intel® Core™ i7-7700K Processor) on version SDK 2.4. Those values I stated above were determined via the |
Which GPU and CPU? |
Sorry, i edited after inital response. |
Ok, I think you can take advantage of the new release of the wrapper that will be released with new SDK in the next days |
Okay great! I look forward to testing this :) |
Does using the notelet instead of the node help with the fps issue? |

Cheers.
