Been looking into this myself cuz bored. If you subtract the UntrackedMemory from the Memory on the client, it should be closer to what TaskManager is displaying from what I’ve seen… I went further down the rabbit hole and found that ResourceMonitor was fairly accurate out the get-go compared to TaskManager…

TaskManager ≈ Memory-UntrackedMemory:

DevConsole, ResourceMonitor, and TaskManager:

I’d like to mention that the first image had the values taken at different times, so for all I know it could’ve been nearly spot on!

Are there any updates on this? The issue has caused a large hinderance when trying to accurately optimize game performance. I accidentally made a duplicate of this bug report, which I’ve now removed and included below. As can be seen, this isn’t an insignificant amount, especially when considering goal for lower end devices.


Description
The amount of memory usage reported by performance stats significantly exceeds the total amount of memory being used by the Roblox application as reported by the device.

Reproduction
Constantly

  1. Join a game
  2. Open performance stats
  3. Observe the amount of memory being used
  4. Open task manager
  5. Observe that hundreds less MB of memory is being used

Expected Behavior
Performance stats should not exceed the amount being reported by the device.

Actual Behavior
Performance stats consistently displays a higher memory usage than is reported by device.
