Hi @nanonansy,
To find the problem open Windows Task Manager → Performance. Scroll down to GPU and have a look at how much Dedicated GPU Memory. Mine is 0.3/2.0 GB as it is an Nvidia GeForce GTX 1050 below Recommended 4GB, or like the RTX2030 8GB.
I believe someone messed around with the UE5 code to change this ie, stopped the message displaying, but Nanite offloads work to the GPU in UE5
