Rendering thousands of objects results in low FPS but also low GPU usage

Just for clarification: The performance of your application is bad since the number of draw calls is too high. There are several existing topics in this forum about draw call reduction e.g.:

Best Way to Reduce Draw Calls?

Hey! So, I’m trying to reduce draw calls in my project. But here’s the catch: I’m using TransformControls in order to move objects. The approaches I can envision are as follows: Create an InstancedMesh for each type of object, and when I select and instance via raycaster do the following: Set the instance as invisible in the instanced mesh, or something similar, then create a mesh with the same geometry and material in its location to be moved by TransformControls. Then reverse it when selec…

Using instanced rendering e.g. via THREE.InstancedMesh is one possible approach to improve performance.
