Studio uses 40+ GB of memory

It first started happening when i had multiple windows with places open. All windows were taking ~40 GB of memory, despite the places being mostly small, barely rendering anything (I was scripting), and my computer only having 8 GB of RAM. Closing the second window would fix the issue, but now it’s doing the same with a single window. It’s making studio become unusable because I have to restart studio every time. plugins are disabled

What Roblox Studio Betas do you have enabled, do you have the new type checking beta enabled? If so does disabling it help? (File → Beta Features)
I’ve seen this issue a bunch and its always the new type checking beta feature.

seems like that and a combonation of another beta? enabling just the type solver beta did make the memory used increase but at a smaller rate, i’m just going to mark it as the solution for now

I suggest you don’t as the engineers will probably ignore it then and not even read your bug report

Hello people, I know this post is marked as solved, but I’m having the same memory leak issue on my MacBook Pro with the M1 chip running macOS Sequoia 15.5.

From what I’ve seen, it really does look like roblox has a memory leak on macOS. Not sure if Rosetta 2 is part of the problem, but I can’t say for sure what’s causing it.


I know it’s just 2GB and not a huge amount, but on my Windows machine (running Windows 10 IoT LTSC), roblox only uses around 1.5GB.

Hello! I’m sorry to hear that you’re running into this problem. Would you be comfortable providing a place file? As Crab_Wrangler mentioned, we’re aware the New Luau Type Solver can use more memory than the old solver. Most of our focus has been on correctness and stability, but we’re pivoting now to focus more on performance and memory usage.

that’s kinda the normal for me :sob:
maybe my computer is just letting it use as much memory as it needs because there aren’t other apps taking a lot of memory. like not letting memory go to waste lol

Yeah, and when you turn the new type checker on… it causes even more issues like syntax errors not being highlighted and autocomplete not working… ironic

Hi! Yes I can provide a place file. Would it be ok if I sent it via DM? I can only remove so much without the problem fixing itself and I don’t want my entire game’s scripts being public. Also, I’ve noticed that with the type solver beta enabled, studio won’t close until I force quit it.

I actually haven’t noticed any errors and I don’t really even know what’s new in the beta… I guess I had it on by default? I’m going to go check out what’s new now.

Weirdly enough, the issues I described seem to only occur in team create projects with the feature on. It seems to be very buggy at this time


its even doing this on scripts that are only 12/13 lines long! there are other scripts in this place too
ignore the debounce thing that is never used haha

Yes it would be ok if you sent it via DM. We’ve also rolled back a recent change that might have caused more memory usage like you’ve observed.
