> 1.heavy means simulator calculation compare to other simulators such as LGSVL Simulator. I felt your simulator is too heavy when we use CARLA with GUI in Linux.

Please provide details of your testing method and the results you got for LGSVL and CARLA. Otherwise neither simulator will be able to validate your claims, find problems, and fix them.

Please be specific. What was hard? Where did you encounter difficulties? If you provide this information, the CARLA developers can improve their documentation and perhaps their build process. If you don’t, nothing can be improved.

Can you provide a video of this? And a video of another simulator to show how it compares.
