Constant Game Lag

[Jamie_Jr (Jamie)]

Hello! I’m currently looking to fix the lag that is within my game.

I have had my 3D-Modelers reduce all of our triangle counts and we are currently still experiencing lag. I have come to think that it is a memory leak or some other type of script lag.

MicroProfiler

I don’t really think it takes a genius to say that this doesn’t look good. (Of course I’m not a genius so I’m not sure what this means)

Memory

18,000 PING!?!?

[EmeraldSlash (Rio)]

For future reference, the ‘lag’ caused by tri-counts and the like affect FPS and client-sided things. Having more can increase server-sided memory, I think, but not with the same devastating effect seen on the client (1 FPS lol)

Ping lag is unrelated, as far as I know, but looking at this thread could change that: https://devforum.roblox.com/t/why-is-roblox-getting-so-laggy/4300

@Maximum_ADHD

Here’s my idea, and I have no idea what I’m talking about honestly.

Because roblox is trying to run everything at 60 HZ, a lot of processing power has to be put into the client to keep it that way. So if it has to render more complex stuff, it might slow down its responses to the server and thus causing latency to increase.

Murder had a lot of latency problems when I first launched it, and I eventually narrowed down that it was caused by the extreme memory usage by the client. After reducing the absurd updating rates in my code, the lag significantly dropped from an average 190ms ping to an average 75-95ms ping.

If your game isn’t running a lot of code and it’s still lagging, I’d advise turning on streaming.

So it could be that you are simply doing way too much.

I’m no expert on this so /shrug

I did some trial and error testing- it seems to me that our current system to apply user morphs lags. I don’t believe that this is the only cause though. I’ll continue testing.

I’ll also be willing to pay substantial amounts of money for help on this.

I really didn’t find much use for that thread sadly.

You could be having issues with garbage collection.

PSA: Connections can memory leak Instances!

Preface I’ve seen several experienced developers not knowing this, or not having a full understanding of what’s going on, so I thought I’d write a dedicated post on the issue of accidentally leaking Instances (so that they are not GCed even when there are no references to them) through lingering event connections. What circumstances cause a leak do -- All good, this part will be GCed just fine local p = Instance.new('Part') p.Touched:connect(function() print("Touched") end) end do -- O…

How do you apply the morphs, and listen for stuff and all of that?

Maybe provide the code if possible so I (and others) can take a look.

[Jamie_Jr (Jamie)]

Whenever a player joins this function would be called…

local function MorphUser(User,Team,Class,Morph,name)
local MorphRoot = Morphs[Team][Class]:WaitForChild(Morph)					
for _,v in pairs(User.Character:GetChildren()) do
	if v.Name == name then
		v:Destroy()
	end
end
local UserMorph = MorphRoot:Clone()
UserMorph.Parent = User.Character
UserMorph.Name = name
if UserMorph:FindFirstChild('Shirt') then
	if User.Character:FindFirstChild('Shirt') then
		User.Character.Shirt:remove()
		UserMorph.Shirt.Parent = User.Character
	end
end
if UserMorph:FindFirstChild('Pants') then
	if User.Character:FindFirstChild('Pants') then
		User.Character.Pants:remove()
		UserMorph.Pants.Parent = User.Character
	end
end
for _,u in ipairs(UserMorph:GetChildren()) do
	if u.Name ~= 'Shirt' and u.Name ~= 'Pants' then
		--u.Middle.Transparency = 1
		for _,p in ipairs(u:GetChildren()) do
			if p:IsA("BasePart") then
			 	local W = Instance.new("Weld",u.Middle)
				W.Part0 = u.Middle
				W.Part1 = p
				local CJ = CFrame.new(u.Middle.Position)
				local C0 = u.Middle.CFrame:inverse()*CJ
				local C1 = p.CFrame:inverse()*CJ
				W.C0 = C0
				W.C1 = C1
			end
			local Y = Instance.new("Weld",p)
			Y.Part0 = User.Character:FindFirstChild(u.Name)
			Y.Part1 = u.Middle
			Y.C0 = CFrame.new(0, 0, 0)
			p.CanCollide = false
			p.Anchored = false
		end
	end
end

EX:

MorphUser(Player,“TFO”,“Heroes”,“Phasma”,“Morph”)

[SteadyOn]

From looking at that nothing screams memory leak. If there is a problem with the morphing it may be to do with calling the function repeatedly, could you show us where the MorphUser(Player,“TFO”,“Heroes”,“Phasma”,“Morph”) is called?

Although very displeasing to the eye, that code also doesn’t seem to be causing your leak, try disabling individual scripts and checking if there is a major change.

[Jamie_Jr (Jamie)]

Whenever a user resets or the morph loads in it lags the server. Thats the main problem

[nin900500 (nin)]

I’ve been having this issue in my game for the past couple weeks.

The server’s ping would skyrocket, and it never ever did that before. I reverted the game 1 month prior to the first occurrence of this bug and my game still has the issue.

[Jamie_Jr (Jamie)]

Yes. The game didn’t lag badly before- now it seems awful.

[SteadyOn]

By the way you should replace the ‘:remove()’ function calls in your scripts as this method is deprecated. This could be a small contributor to your issue as the remove function doesn’t properly remove instances like ‘Destroy()’ does.

Also, looking at the characters after morphing, what is the distribution and amount of welds in the morph?

[Jamie_Jr (Jamie)]

That shouldnt cause actual lag (such as animations not running & chat being delayed) It should only cause FPS lag I though?

I will update the remove function.
