XBOX/Microsoft UWP App has massive memory leaks

Roblox if launched via the Microsoft store app or on XBOX will have DOUBLE the memory usage. Usually resulting in crashes on the XBOX app as the memory limit for the app is 5GB. This is making my game unplayable for XBOX players, even if they are on a Series X/S.

This happens only in the Microsoft Store or XBOX version.
I am not sure when this started happening, but I have just heard of it now after I have enabled XBOX support for my game.


  • Join the game on the UWP app or XBOX.
  • Watch the memory usage.
  • Typically after 2-4 minutes the app will crash.

Thanks for the report! We’ll follow up when we have an update for you.


Has there been a fix yet? This is greatly affecting my players who are complaining a lot about crashing on their console.

I don’t know if this is relevant, but I also noticed Xbox takes an awful lot of memory in-games.
For example, the baseplate template from Studio has the Xbox RAM usage go to 1.5 GB RAM compared the 900MB RAM on PC, according to developer console, which is quite a huge sum above what the PC app would get.
I have also noticed, that over time, that 1.5GB ram would keep slowly increasing every few seconds.
Upon staying in the baseplate a few minutes, the ram went up to 1.8GB


Hello, we made a change in late September that may have addressed this issue. Please let us know if it persists, thank you!
