1:16:57kknewkles I mustered up one more. How come The Witness has 4GB RAM as minimum requirement? I don't doubt it has great optimization (as Jon is an apex-level programmer). Is it because nowadays everyone has 4 gigs at least and they thought it's unfeasible or too limiting to go below that? What can be the design behind that requirement?
