Playtests Increase Loading Time + RAM Usage Drops Over Time

WlZ_ONE · April 30, 2025, 1:36pm

After each consecutive playtest in Studio, my game’s loading time increases. The first load is fast, but with each test afterward, the load time gets longer and longer — sometimes doubling or tripling. This isn’t just happening to me — other developers on my team are experiencing the exact same issue.

For clarity, the loading time screenshots I’m sharing below were all taken from the same Roblox Studio instance, without restarting Studio between tests.

FYI I’m not running any plugins.

Expected behavior

If everything were working correctly, I would expect subsequent playtests to either maintain the same loading speed.

Thank you for filing this, it sounds very disruptive. We’ll take a look.

Can you send us what Betas you’re currently enrolled in, and possibly your place file in a Private message for repro?

Hey, sorry for the delayed reply

I’m currently enrolled in all the Studio beta features except for the following:

New Luau type solver
New Studio camera controls
Haptic effects
CreateAssetAsync Lua API
Acoustic simulation

Unfortunately, I can’t share the .rbxl file, but just for context, the game is quite large and has a lot of assets stored in ReplicatedStorage.

Thank you for the Beta list!

To troubleshoot, can you please verify if this is still happening without the New Type Solver?

Thanks again!

I am also having this issue when testing my game Navy Simulator. I will try to send the place file in a private message if it isn’t too large. I do not have the New Type Solver beta feature enabled.

My beta list:

Dragger QoL improvements
Incremental typechecking and autocompletion in studio

2 Questions:

How are you measuring the loading time here?
Could you send logs us logs (via direct message) from a session where you see this bug happen?
