Questions about 3D View performance and scene configuration

[Enei7]

I have another question about the performance of the built-in 3D View, not the UE Live View.

When I open the demo scene, the map in the 3D View looks much more detailed than the one shown in the README. It contains many buildings, road details, textures, trees, and ray/beam visualization paths. Even when I only rotate or switch the camera view in the 3D View, the interface becomes quite slow and laggy.

I am running the simulator on a machine with an NVIDIA RTX 3090 GPU. Could you please clarify whether this behavior is expected for the default demo scene?

I would also like to ask:

1、Is the 3D View using hardware OpenGL/GPU rendering by default, or are there any additional configuration steps required?
2、Are there recommended parameters to reduce the scene complexity, such as map resolution, level of detail, mesh simplification, ray/beam visualization density, or 3D View update frequency?
3、Is the scene used in the README different from the default demo scene? The current demo scene seems much more complex and may be causing the low interactive frame rate.
4、Could you provide the hardware configuration used for your demo videos or experiments?

Thanks in advance for your help!

Thank you for raising the issues! These do help us to identify and fix potential problems.

As long as your GPU is working properly on your computer, SimART will use it automatically. After checking and optimizing the code, the CPU usage has been reduced when dragging, rotating, and viewing the scene in the 3D view, so it should now be much smoother than before. I have just submitted a commit to fix this, so please make sure you have pulled the latest version.

An NVIDIA RTX 3090 should work very well with our default scenes and settings. We used an NVIDIA RTX 5070 for recording the video demo (to show the best performance of SimART), but we also tested it on an NVIDIA RTX 3060 Ti, and it was able to run the simulations properly.

The scene is the same as the one shown in the README. I updated the sample maps last week, but the changes mainly focused on optimizing the textures/materials of the scene. And thank you for the reminder, I will update the figures in README soon.

I hope that this may help!
