Questions on Performance with CFraming

Help and Feedback Code Review

I’m making a camera script that, when the player aims, faces their character to whatever direction the camera faces for the duration of them aiming. To do that, I repeatedly call this function:

--rotates root_part so that it's facing same direction as camera
--possibly use tween service to smooth this out :)
local function faceCharacterWithCamera()
	local root_part : BasePart = (current_character.PrimaryPart :: BasePart).AssemblyRootPart :: BasePart
	local root_part_position : Vector3 = root_part.CFrame.Position
	
	local look_here : CFrame = current_camera.CFrame * CFrame.new(0,0,-10000)
	local look_here_position : Vector3 = look_here.Position
	
	root_part.CFrame = CFrame.lookAt(root_part_position, Vector3.new(look_here_position.X, root_part_position.Y, look_here_position.Z))	
end

Currently, it’s tied to RunService.RenderStepped in a local script. I was just wondering if, with a server full of people playing, this would become very taxing and affect performance? If not, would adding Tweening so that the player’s character doesn’t just jump around affect performance?

Since this script is running on the client, the amount of people in the server has no effect on performance. If it’s working fine right now, it’ll keep working fine.

Ah, I didn’t think about that. Thank you!
