I see. I’m guessing the reason why it’s difficult for me to track this performance penalty of using the default camera script is because most of the price is paid in GC, which is as opaque as it gets for performance tracking. If the proposed change to making CFrame a native type goes through eventually, this difference will become negligible if I’m not mistaken.
I suppose until then, your camera system is indeed a big boost. I don’t think most people are that concerned about performance, but as a proof of concept, it is well done. Nice!
