LinearVelocity used for my knockback is very laggy

[AlexiSanchezReal (DHNFJNSDDSA)]

I’m encountering a problem with the knockback system in my combat mechanics. I’ve implemented linear velocity to handle knockback effects, but it appears to be quite laggy, as shown in the video below. The knockback should be smooth, but instead, it feels laggy. I suspect the issue might be related to how the velocity is being applied or updated, but I’m not entirely sure where things are going wrong.

Here is my code if needed.

function Combat.Damage(Player, CharacterHit, Damage)
	local Humanoid = CharacterHit:FindFirstChild("Humanoid")
	local HumanoidRootPart = CharacterHit:FindFirstChild("HumanoidRootPart")
	Humanoid:TakeDamage(Damage)
	
	if Damage == 20 and CharacterHit then
		local Attachment = Instance.new("Attachment", HumanoidRootPart)
		local LinearVelocity = Instance.new("LinearVelocity", Attachment)
		LinearVelocity.MaxForce = math.huge
		LinearVelocity.VectorVelocity = HumanoidRootPart.CFrame.lookVector * 100
		LinearVelocity.Attachment0 = Attachment
		
		Debris:AddItem(LinearVelocity, 0.25)
	end
end

try waiting a few minutes in the game and then try the knockback, if its fine, then just know that the server just began and its kinda slow, so u need to wait a little bit, but otherwise its fine then

BodyVelocity looks smoother than LinearVelocity, but it's all glitched

I am making a combat system where when you punch you go a little forward. *i have tried using LinearVelocity, but it looks laggy, so when i switched to BodyVelocity it looked smoother. When i try to use two bodyvelocity, one for the small dash attack, one for the knockback cause by the parry, the knockback doesn’t work; when i try to use one bodyvelocity and one linearvelocity, the knockback is all buggy, and when i use two linearvelocity it’s all good, but on other clients it is so laggy and …

try to go to workspace, and enable “MoverConstraintRootBehavior” in the properties
