while true do
local Time = elapsedTime()
local WaitDt = game:GetService("RunService").RenderStepped:Wait()
local NewTime = elapsedTime()
local ElapsedDt = NewTime - Time
print("Pct Diff. in measured time: ", 100*(ElapsedDt - WaitDt)/ElapsedDt)
end
Intuitively these two methods of measuring the time elapsed between Time and NewTime should be close to identical, but in practise it varies randomly by ±/10%. Why is there such a difference?
