Today games need more than 512MB of GPU and that’s really putting a threat on our application.
Do you know if there’s any rational cause to limit the GPU upload size?
How can this be changed?
I think you should re-post your question in the official AIR Discussions here: https://github.com/airsdk/Adobe-Runtime-Support/discussions
There you can reach out to the maintainers of the AIR SDK directly.
