NPC stuttering for some reason

[RocketSlither (Distinguished_Gent)]

I am making an NPC, and for some reason when it has higher speed than the player it starts to stutter. all of the parts in the character network owner are set to nil.

The players Sprint speed is 30 whilst the monsters is 37.5

I didn’t make the original code, but I modified it a bit.

vid of issue:

Code of main pathfinding loop:

while task.wait() do
	local enemytorso = GetTorso(HumanoidRootPart.Position)	
	if enemytorso ~= nil then -- if player detected
		Target = true
		Humanoid.WalkSpeed = NPC_Settings.ChaseSpeed
		if enemytorso.Parent:FindFirstChild("_Chasing") == nil then
			local Value = Instance.new("NumberValue",enemytorso.Parent)
			Value.Name = "_Chasing"
			Value.Value = 1
		else
			enemytorso.Parent:FindFirstChild("_Chasing").Value = 1
		end
		
		isWandering = 1
		local function checkw(t)
			local ci = 3
			if ci > #t then
				ci = 3
			end
			if t[ci] == nil and ci < #t then
				repeat
					ci = ci + 1
					task.wait()
				until t[ci] ~= nil
				return Vector3.new(1, 0, 0) + t[ci]
			else
				ci = 3
				return t[ci]
			end
		end
		
		path = Pathfinding:ComputeAsync(HumanoidRootPart.Position, enemytorso.Position)
		waypoint = Pathfinding:GetWaypoints()
		oldpoints = waypoint
		local connection;
		
		local direct = Vector3.FromNormalId(Enum.NormalId.Front)
		local ncf = HumanoidRootPart.CFrame * CFrame.new(direct)
		direct = ncf.p.unit
		local rootr = Ray.new(HumanoidRootPart.Position, direct)
		local phit, ppos = game.Workspace:FindPartOnRay(rootr, HumanoidRootPart)
		
		local Distance = (math.ceil((HumanoidRootPart.Position - enemytorso.Position).magnitude))
		
		if NPC_Settings.Lunge and Distance < NPC_Settings.MiniumLungeDistance and Humanoid.PlatformStand == false then
			Humanoid.PlatformStand = true
			local LinearVelocity = HumanoidRootPart.Attachment.LinearVelocity
			LinearVelocity.Enabled = true
			LinearVelocity.VectorVelocity = (-(HumanoidRootPart.Position - enemytorso.Position) * NPC_Settings.LungeIntensity) + NPC_Settings.LungeOffset
			if HumanoidRootPart:FindFirstChild("Lunge") then
				HumanoidRootPart.Lunge:Play()
			end
			task.delay(.1,function() LinearVelocity.Enabled = false end)
			task.delay(1,function() Humanoid.PlatformStand = false; Humanoid:ChangeState(Enum.HumanoidStateType.GettingUp) end)
		end
		
		if path and waypoint or checkw(waypoint) then
			if checkw(waypoint) ~= nil and checkw(waypoint).Action == Enum.PathWaypointAction.Walk then
				Humanoid:MoveTo( checkw(waypoint).Position )
				Humanoid.Jump = false
			end
			
			if checkw(waypoint) ~= nil and checkw(waypoint).Action == Enum.PathWaypointAction.Jump and NPC_Settings.CanJump and Humanoid.Sit == false then
				Humanoid.Jump = true
				connection = Humanoid.Changed:connect(function()
					Humanoid.Jump = true
				end)
				Humanoid:MoveTo( checkw(waypoint).Position )
			else
				Humanoid.Jump = false
			end
			
			if connection then
				connection:Disconnect()
			end
			
		else
			for i = 3, #oldpoints do
				Humanoid:MoveTo(oldpoints[i].Position )	
			end
		end
	elseif enemytorso == nil and NPC_Settings.canWander then -- if player not detected
		Target = false
		isWandering = 0
		path = nil
		waypoint = nil
	end
end

Solution:

I made it so if the NPC can see the player it just walks straight towards them, else they path finds
