I’ve been experiencing a problem for quite some time now after installing some new RAM and I’m trying to investigate it to the best of my ability.
Most of the threads I see on dev forum point to plugins when RAM is getting exceptionally high on studio. I’ve removed all of the plugins I’d consider “dodgy” and only kept the very popular ones. My question is that apart from script injection, do plugins have permissions to do something outside of script injections that may cause my RAM to explode like this?
It goes to my max of using all 64 of my RAM within minutes of opening Roblox Studio to the point I physically can’t use it anymore - I’ve never experienced an issue like this before. I always end up closing studio from task manager as it refuses to close in the usual way when clicking X. Is this a bug or an issue with my system?
Plugins have way more system access than regular scripts, so it’s best not to install suspicious ones. A plugin may have a memory leak somewhere or is intentionally executing malicious codes which can be many things, including memory bombs.
A friend of mine is experiencing the same issue and brought it up to me. I did some testing and observed it too. Notably, gcinfo does not match the increase. Are you able to create bug reports? If so, I recommend creating one.
It is very unlikely that Roblox Studio plugins will allocate this much RAM. I will assume you mean 64GB of RAM. From what I can imply, it could (very likely, imho) be a bug on the studio itself. I may not be a Roblox developer, but the memory usage is not the best already on the engine by itself. I’m talking that simply opening the studio is already enough reason to be at 2GB of usage on my system, and on a basic baseplate I’m already looking at 4GB of RAM, even when my plugins are insanely light, and I never had issues like this.
I have enough RAM to just throw away myself, and I have allocated plenty of a page file in case I ever ran into memory issues, but the times I started having severe memory issues were when I was doing my own stuff (i.e., RbxStu or modifying flags for no reason).
Perhaps you may have a fast flag set, and it is causing this issue? I do know from some exploiting circles that a crash that occured a few days ago by just playing the game originated from a fast flag being incorrectly set (and thus deployed to users!)
for reference, this is what an exploiter server announced the day the crashes started occuring (10/4/2025):
Set DFFlagGeometryBuffersTelemetry to false
or alternatively RobloxPlayerBeta.exe+0x5A7CBE8 to 0
This crash is caused by an access violation in the telemetry
This is very highly likely an engine issue, not something that can be caused by a plug-in or Luau. Don’t try to check gcinfo for this kind of thing, because this far escapes scripting, and it’s more involved with the engine just being , probably a flag just messing with you in the end.
We’ll need to know much more about the system, including the plugins you’ve left. We don’t have any general issues like this, and there would be a lot of alarm bells going off if this was a general issue. It sounds like you don’t have a specific place that’s doing this - but is it happening on base plate or a clean template of any sort?
Plugins can generally do a lot of things, including taking up lots of RAM (or calling methods that can take up RAM). It could also be a specific artifact of your workflow, either with plugins or without. Are there any common behaviors you’re using within a few minutes of using Studio that seem to trigger the issue? Specific features, specific plugin features, etc? Does it happen without you doing anything? Does it happen every time or only some of the time? Are any other errors thrown at this time when its happening.? (Possible bad error handling is triggering some kind of recursive failure that’s eating memory). A log file will help us diagnose this.
Absolute best thing would be to eliminate the variables complete - a known place, no plugins, etc. If it can’t be done there, then that points to one of the things you’ve eliminated. Otherwise if its only a specific place it could be something that leaks when that place is being tested, assuming testing is part of what triggers the issue.
I’ve got to the point where I’ve just removed all my plugins because I was fed up and the problem remains unfortunately. I have no idea and wouldn’t even know where to start in regards to the patterns of the behavior of the RAM increases. I’ve followed up with further details in my bug report here that provides much more detailed information and that is where I’m currently at:
This does also seem to be a general issue but not on the scale that I seem to be reporting as reported 8 days ago Major Memory Leak in Roblox Studio Windows 11 so clearly this needs urgent attention.
The behaviour of what is eating my RAM is very case by case basis - some games it won’t do it all, some games it will wait 10-30 minutes before starting to eat and often it will just go immediately and start eating RAM at increments of 100MB each second. I will send a logo file to your messages.
, probably a flag just messing with you in the end.
