Are there any substitutes for .RenderStepped?

I'd like to use something similiar to .RenderStepped in a normal script - problem is that other alternatives are very choppy, like this:

while wait() do
x.CFrame = y.CFrame *CFrame.new(0,0,5)
end

Stepped

local rs = game:GetService("RunService").Stepped
while rs:Wait() do
	x.CFrame = y.CFrame *CFrame.new(0,0,5)
end

BindToRenderStep (local only)

local rs = game:GetService("RunService")
rs:BindToRenderStep("name", 100, function()
	x.CFrame = y.CFrame *CFrame.new(0,0,5)
end)
