There may be times when Beyond CAD starts to preform slowly and it becomes laggy with a low frame rate. There may be several causes to this, each which has its own solution(s) that can be tried separately or in conjunction. 

  • Long sessions- we are trying to identify and fix this issue, but sometimes, after long sessions of using Beyond CAD, the frame rate can start to drop. This may be related to doing a number of video renders in the same session but regardless, there is an easy fix. Just make sure the file is saved and close down Beyond CAD. When you reopen Beyond CAD it should be running smoothly again.
  • Underpowered computer - In the event that the computer you are using Beyond CAD on is underpowered, there will likely be limitations on how complex the scene can be before performance starts to slow. For long term Beyond CAD use we recommend investing in a capable machine that can handle more complex projects. Learn more about the recommended specifications here.
  • High number of assets - For more complex scenes, the number of assets can start to affect performance of working within the Beyond CAD editor. This is especially true of placing high numbers of trees which can make for realistic forests but also slow performance. The recommended solution for handling scenes with a high number of assets is to place each type of asset on its own layer (ie Layer 1 is buildings, 2 is Trees, 3 is cars and so forth) and then turn off layers for assets that aren't being used. This will allow for much higher performance while building a Beyond CAD scene without removing assets. Remember to turn on all necessary layers before rendering.
  • High poly count import meshes - If imported meshes (FBX, OBJ, DAE...) have a high polygon count (ie millions of triangles) the amount of data can cause performance issues with Beyond CAD or any other 3D software. Running the meshes through an optimization workflow in 3DS Max or Blender can possibly help reduce the poly count and improve overall performance. The power of the computer you are using will also affect how well Beyond CAD handles complex meshes. 
  • Large texture sizes - If imported files have textures with large files sizes (especially aerials) performance can be affected. Compressing the images used for these textures may help with performance as well as placing these objects on layers and turning the layers off.
