Hello!
I am currently making a space game, with visible planets, that are made out of Viewport Frames, inside a Billboard Gui, which is inside a ScreenGui. A script inside is calculating the planet’s position relative to player’s current position and updating everything using RenderStepped event. The problem is, that when I set my graphics quality to minimum, everything gets very laggy. Im pretty sure RenderStepped event slowed down by a lot.
Here is an example video, of the problem:
Any ideas on how could I fix the lag, and make my game playable?
Thanks for help!
Since you’re in Help and Feedback > Scripting Support, mind showing the problematic code? I tested on my end (in studio and on the client), and I don’t have this issue.
local player = game.Players.LocalPlayer
local camera = game.Workspace.CurrentCamera
local model = script.Parent
local planets = game.Workspace.Planets
local covermindistance = 10000
local newcamera = Instance.new("Camera")
newcamera.Parent = model
for i,v in pairs(model:GetChildren()) do
if v:IsA("ViewportFrame") then
v.CurrentCamera = newcamera
end
end
local campart = Instance.new("Part")
campart.Anchored = true
campart.Transparency = 1
campart.CanCollide = false
campart.Parent = newcamera
model.Adornee = campart
model.Size = UDim2.new(0,camera.ViewportSize.X,0,camera.ViewportSize.Y)
camera:GetPropertyChangedSignal("ViewportSize"):Connect(function()
model.Size = UDim2.new(0,camera.ViewportSize.X,0,camera.ViewportSize.Y)
end)
game:GetService("RunService").RenderStepped:Connect(function()
-- example body
local distance = (camera.CFrame.Position-planets.ExampleBody.CenterPos.Value).Magnitude
if distance<0 then
distance = -distance
end
if distance > covermindistance then -- check if camera is far away enough
model.ExampleBody.Visible = true
local pos = planets.ExampleBody.CenterPos.Value:Lerp(camera.CFrame.Position, 0.8)
model.ExampleBody.Part.Position = pos -- set position of the part in the viewport frame
else
model.ExampleBody.Visible = false
end
-- Camera
newcamera.CFrame = camera.CFrame
campart.CFrame = newcamera.CFrame*CFrame.new(0,0,-500)
newcamera.FieldOfView = camera.FieldOfView
end)
I can change my Frame Rate Limit to a higher one. But users on weaker devices won’t really be able to. I need to fix this, mainly for people who don’t max out their graphics.

I changed it so it uses FindFirstChild for safety, cached the variables for better performance, added checks to stop unnecessary updates, made the size update a function, and now the camera and visibility only update when needed
In short, I optimized it a little bit
But idk its works or not? because i dont have these viewports
Could you send me a location file? I can’t get the provided script to do what you’re looking for. In any case, if each ViewportFrame is a Planet, this causes the FPS to be deprioritized when updating the Viewport. An example was once I made a weapon visualizer where the weapons only rotated, but it had weird “gaps.”
I realize that. I tested turning the camera and the cubes continue to move across the screen smoothly. Though, I believe my example was oversimplified and wasn’t what he was trying to do.
I’m not sure how to fix your code, but I’m assuming you’re using ViewportFrames to render objects that are very far away. You might benefit from supporting this feature request:
I understand. So with a for loop, you update the object’s position in the Viewport based on where it is in the Workspace? Can you send me a screenshot of your Workspace?
