How to make ball movement smooth on all fps?

Help and Feedback Scripting Support

I’m using AlignPosition w/ 2 Attachments, 1 on the client-sided ball and the other iterating through a curve. My problem is that the movement is only smooth when on 60 fps, I was previously using a for loop and tried switching to runservice for deltaTime but that didn’t work.

Script:
(Commented Out are the two loops I tried)

local function PingPongVelocity(Ball, Time, SFX, P2)
	--print("Start Velocity")
	Ball.Anchored = false

	local newVelocity = Ball:FindFirstChild("AlignPosition")
	local BallAttachment = Ball:FindFirstChild("Att1")

	local startTime = time()

	local steps = 10
	local speed = game.Workspace.ServerBalls:FindFirstChild(Ball.Name).Speed.Value
	local duration = (Time - .25)
	local delayPerStep = duration / steps
	
	--for i = 1, steps do
	--	newVelocity.Attachment1 = folder["Part"..i]:FindFirstChild("Attachment")
	--	task.wait(delayPerStep)
	--end
	
	--local i = 1
	--local conn
	--conn = RunService.RenderStepped:Connect(function(dt)
	--	if i == steps then
	--		conn:Disconnect()
	--	end
	--	newVelocity.Attachment1 = folder["Part"..i]:FindFirstChild("Attachment")
	--	i = i + 1
	--	task.wait(delayPerStep * (dt*60))
	--end)
	
	
	local VFX = script.Attachment:Clone()
	VFX.Parent = game.Workspace
	VFX.Position = P2
	VFX["Whole swirl"]:Emit()
	game.Debris:AddItem(VFX, 1)

	--print("TIME: " .. time() - startTime)
	if SFX then
		local sound = game.Workspace["Ping pong sound effect"]:Clone()
		sound.Parent = Ball
		sound:Play()
		game.Debris:AddItem(sound, .5)
	else
		local sound = game.Workspace["ping pong hit sound"]:Clone()
		sound.Parent = Ball
		sound:Play()
		game.Debris:AddItem(sound, .5)
	end
	--Ball.Anchored = true

end

240 FPS V. 60 FPS

looks great bro. i didnt see any difference between the 240 fps and 60.

I don’t think the video shows the 240 fps long enough but it’s noticeable snappier as it doesn’t follow the curves oppose to 60 fps

Longer 240 FPS Video:

Decided to just use a bezier tween module which actually solves another problem of the ball looking wonky at high speeds.
