I use bezel artwork on everything. If it doesn't exist, I make it. At 1080x1080, I've managed to get all instructions readable, though sometimes I have to tinker a bit to do it - scaling an instruction card a little larger than it actually was, for example.
As nexusmtz says, a lot of the bezels out there are very high res - I found that contributed a bit to loading time. If you know the resolution you're going to be running it at, you can resize it down to your exact target size in an image editor and it'll load a lot faster, as well as giving you the chance to clean up the sharpness to your liking. It is labor intensive, though.
