First, insert a ScreenGUI:
Second, insert a TextLabel, and customize it:
Third, insert a LocalScript into the TextLabel:
Fourth, copy and paste this code into it:
local RunService = game:GetService("RunService")
local start = tick()
local updaterate = 0.5
local average_amount = 5 --Higher the average, the more accurate the fps will be!
local fps_table = {}
RunService.RenderStepped:Connect(function(frametime)
if tick() >= start+((updaterate)/average_amount) then
local fps = 1/frametime
table.insert(fps_table,fps)
end
if tick() >= start+updaterate then
start = tick()
local current = 0
local maxn = table.maxn(fps_table)
for i=1,maxn do
current = current+fps_table[i]
end
local fps = math.floor(current/maxn)
script.Parent.Text = fps
fps_table = {}
end
end)
Finally, test your game and see the results:
Note: I had lag spikes from minimizing and maximizing the window, this is normal
Play around with these variables:
local updaterate = 0.5
local average_amount = 5 --Higher the average, the more accurate the fps will be!
This script basically takes a certain update rate, and divides it by the amount of fps to be checked. It adds all indexes inside the table it made, and divides it using table.maxn() . It then uses math.floor() to get a single integer and sets the text to be the fps.
