When I open studio and check task manager, my ram usage goes up by about 3GB just on the homepage. Task manager is only reporting about 800mb of usage. Lets say I have a project open, task manager reports I’m using 2gb-5gb, my memory goes up by 12gb.
System specs
OS: Windows 11 Pro
CPU: I7 13700f
RAM: 64gb DDR5 6400

Expected behavior
Should only be using the reported amount of ram that task manager is displaying.
I’ve been having this problem since yesterday. A single project (almost empty, except for the UI) was consuming 4.5 GB of RAM, and having two projects open at once used 6 GB. I have 16 GB of DDR5 RAM (which isn’t enough for my needs), but Studio’s consumption is unreasonably high—so much so that I got a Blue Screen of Death, and later, with three Studio instances open simultaneously, I got a Roblox pop-up saying there was no RAM available.
This same exact issue has been happening to me as well. I’m on a MacBook Pro M3 Pro with 32GB of unified memory. Roblox Studio is taking up at least 12GB whenever Studio is open, no matter the project.
It’s expected that there is a difference between the delta in system memory usage and the private memory usage of the Studio process - because these are different measures of memory usage. The graph on the performance page measures total physical memory consumption, whereas the memory number on the processes page only counts private working set (i.e. the amount of physical RAM that specific Studio process has exclusive access to). These can differ because some of the memory that Studio allocates is marked as sharable - this memory is counted on the Performance tab but not on the Processes tab.
You can see this sharable memory by switching to the details view and selecting the appropriate columns by right clicking - here’s an example:
That said, the difference here between these two memory usages is quite extreme - as you can see from my example I would expect the extra memory to be on the order of a few hundred megabytes, not gigabytes. Could you post the size of your shared working set from the details view in the private messages?
What are the labels on the yellow and red columns here? I would guess “Private memory” and “Commit charge” (or total memory), right? That would seem to match your video. That’s a very surprising amount though. I will follow-up in DMs.
My studio is also using much more memory than expected (anywhere from 13-16 gigabytes of ram).
This issue only appeared when updating Studio to the latest version, though it’s also entirely possible that this issue was introduced from an earlier version that I had not yet updated to.
Are there any updates on this? Our dev group at AxoSun is experiencing an issue identical to this across our development files, but it doesn’t appear to happen in my personal build files (with a lot lower assets). However, most of the assets in these places are in replicated or server storage as they aren’t intended to be always active (maps, meshes, tools, etc.). This issue began around 5 days ago after updating studio, but we had also just had our games unflagged from “IASSinking” being set to false, so that may also be related? My immediate thought is our various meshes/textures in storage are being cached entirely in memory, but I’m not sure what could be causing this.
If it’s happening in a specific place rather than all studio sessions it is likely a different bug than the OP. You should file a separate report with the impacted place attached in the private message section so that we can investigate it.
According to @AB_XIl this issue has stopped reproducing for them, so I will be closing this ticket as “cannot reproduce.” To the others in this thread: If you continue to see excessive studio memory usage then please make new threads with the details.
