I understand you can use approximately 5GB of RAM in Xbox Dev Mode, but it only lets me use 1.3GB. screenshot.User's image

    Hi @Elias Benjamin Lopez Perez .

    In Dev Mode the RAM budget depends on whether your UWP is running as an App or as an Xbox Live Creators Program game.

    Microsoft’s UWP-on-Xbox resource allocation doc states the foreground memory caps are:

    • Apps: 1 GB
    • Games: 5 GB

    So if your package is currently treated as an App, seeing ~1–1.3 GB available (like your screenshot) is expected. The “~5 GB” number applies only when the title is running under the Creators Program game category, not for normal UWP apps in Dev Mode.

    Can you doublecheck if your program is in the correct category?

    If you found my response helpful or informative, I would greatly appreciate it if you could follow this guidance or provide feedback.

    Thank you.
