Hello!

How might I log a player’s FPS?
Like it would set a variable to the current FPS and a variable to the previous FPS, and it would go in a loop.

Thanks!

Do you mean something like this?

local fpsCurr = 0
local fpsLast = 0

game:service("RunService").RenderStepped:Connect(function()
    fpsCurr = fpsCurr + 1
end)

while true do
    wait(1)
    print(fpsCurr)
    print(fpsLast)
    fpsLast = fpsCurr
    fpsCurr = 0
end

There is a lot of posts about your topic. Using this Post about FPS, It appears that there there is 3 ways to do this:

You could get the PhysicsFPS:

workspace:GetRealPhysicsFPS()

That this is probably not what your looking for, but someone else linked a script to get the Clients FPS:

local RunService = game:GetService("RunService")
local FpsLabel = script.Parent

local TimeFunction = RunService:IsRunning() and time or os.clock

local LastIteration, Start
local FrameUpdateTable = {}

local function HeartbeatUpdate()
	LastIteration = TimeFunction()
	for Index = #FrameUpdateTable, 1, -1 do
		FrameUpdateTable[Index + 1] = FrameUpdateTable[Index] >= LastIteration - 1 and FrameUpdateTable[Index] or nil
	end

	FrameUpdateTable[1] = LastIteration
	FpsLabel.Text = tostring(math.floor(TimeFunction() - Start >= 1 and #FrameUpdateTable or #FrameUpdateTable / (TimeFunction() - Start))) .. " FPS"
end

Start = TimeFunction()
RunService.Heartbeat:Connect(HeartbeatUpdate)

or

function getFps()

return (1/game:GetService("RunService").RenderStepped:Wait())

end
local FPS = getFps()

@OfficialPogCat @TheeDeathCaster

Thank you for both of your responses.

However, I am not sure either of your solutions worked.
Basically, I am trying to set the last 3 instances of the player’s FPS. Ex:

CurrentFPS: –
LastFPS: –
LastLastFPS: –

Let me know if this helps.
Thanks!

-- written in the textbox, might be trash and no idea if it works!

local CurrentFps = 0
local LastFps = 0
local LastLastFps = 0

game:FindFirstChildOfClass("RunService").PreRender:Connect(function(DeltaTime)
LastLastFps = LastFps
LastFps = CurrentFps
CurrentFps = 1 / DeltaTime

print(CurrentFps, LastFps, LastLastFps)
end)

It doesn’t seem to be working…

I’m not sure why it acts like that, but I think it does work, or at least it did what you asked for.
Unless there’s a big lag spike it won’t be so noticeable, after all it’s only 3 frames.

Yeah, let me rephrase.

So basically, this code will get 3 variables, FirstFPS, SecondFPS, and ThirdFPS, it will print this every 3 seconds, bc FPS = frames per second.

It is kinda hard to explain, but if you have any more questions feel free to let me know.

#9

no. it will print the current value of those 3 variables every time ur screen is rendered.

But is there a way to do that?

local CurrentFps, PastFps, PastPastFps 
function getFps()

return (1/game:GetService("RunService").RenderStepped:Wait())

end

repeat
PastPastFps = PastFps
PastFps = CurrentFps
CurrentFps = getFps()
task.wait(0.1)
if PastPastFps ~= nil then
print("Current: "..CurrentFps.." Past: "..PastFps.." PastPast: "..PastPastFps)
end
until false
