Avatar FOP 7700s win11 terrible performance

Has anyone managed to play this game on the 7700S on Windows 11 ?
I can’t get it to use the 7700s, it always loads the 780m.
I tried DDU + reinstall of drivers, forcing the GPU in windows options, in amd adrenalin software… Nothing worked.

Strange thing is that I can’t change the in game resolution, nor the window mode (Full Screen always revert to Windowed Full screen automatically).

For anyone wondering, I managed to fix the issue by setting the iGPU memory mode from ‘Gaming’‘ to “Auto” in the BIOS. It seems that the game takes the GPU wich has the greater dedicated memory available…
