Really? Im surprised at that. Compared to ray-tracing shadows and rendering translucent 3D polygons at 120fps, Finale's demands are quite light: it's putting lines and text onto a page, in a single, solid colour!
Apart from the number of pixels in today's large displays, surely not much has changed from the requirements that Finale was making of hardware in the early 90s.
Even the worst available GPU today has got to be equal to a decent one ... what, 5 years ago?
And speaking of the worst available - as a Mac user, I've got an Intel integrated GPU, which everyone says are terrible. But it's sufficient to run two 4K displays, hundreds of Windows, large Affinity Publisher documents in full colour; Photo editing, and even the odd game or two. I'm not aware of anything it ought to be doing better.
