A BIOS update is now available for Acer Swift 3 SF315-41 series laptops powered by mobile AMD Ryzen APUs that updates the AMD SMU version to 2.11. This removes the 256 MB VRAM limitation for the integrated Vega GPU and allows it access use 1 GB of system RAM as the video buffer. While the new option is indeed welcome, it hardly makes any difference when it comes to practical usage.

Why does the author write "it hardly makes any difference when it comes to practical usage" without giving any sort of evidence for this. When I had an iGPU (AMD A10-5800K), there was a significant performance difference between running it at 256MB and 512MB VRAM. There was little difference between 512MB and higher.
