Make sure the all the layers on top of the one you're modifying are hidden.Only activate channels on fill layers that you actually use.Getting the official advice out of the way. Monitor Resolution (in case this factors in somehow) : 1366 x 768.And besides, most people who can afford the $20/month it takes to use substance painter, probably have at least decent modern hardware to run Substanceīut for the remaining ~40/20% that don't for a bunch of reasons, and maybe the remaining 150% that acquired substance through shadier means, for shame!, this guide is for you.

That's always going to take some computing power.
