What happened

I'm trying to get InvokeAI to properly use the full 96 GB of unified GPU memory on an ASUS ROG Flow Z13 with a Ryzen AI Max+ 395 and Radeon 8060S.

System:

ASUS ROG Flow Z13 (2025) CPU: AMD Ryzen AI Max+ 395 GPU: AMD Radeon 8060S Graphics GPU architecture: gfx1151 Unified GPU memory: 96 GB RAM: 128 GB LPDDR5 OS: Windows 11 Pro 25H2, 64-bit Python: 3.12 AMD Windows driver: 32.0.23033.5002

I want InvokeAI to use the Radeon 8060S's large unified memory pool instead of being limited to the smaller amount of memory it appears to make available to the application since it's capping at 32GB. I've used LM Studio and other programs without any issues and I could see the full 96GB available to use in those programs.

What you expected to happen

I expected to be able to use the full amount of RAM currently in my system.
