When moving my camera, I notice my frames will sometimes drop to 30-40 FPS. As soon as I stop moving the camera, it will go back up to 60 FPS.
This only began happening yesterday, and has persisted across my laptop and desktop computer. It only seems to happen when around certain meshes.
In the above video, you can see my frames in Studio drop as soon as I go near the pan with the billboardgui.
