Digital Foundry is one of the premier online teams for technical analysis of games and hardware, often focusing on current-generation gaming to assess performance, frame rates and more. It's now turning its eye to some retro games, too, which provides some interesting context on classics from past generations.
In its most recent video it looks at two of Rare's most iconic N64 games - GoldenEye 007 and Perfect Dark. It's an interesting watch, especially as the analysis highlights just how low frame rates were in some of these titles, in addition to the improvements Rare made once it got use to the hardware.
Technical analysis is all relative, of course - standards and expectations of game performance were very different in the mid-to-late '90s, which can mean a rude awakening when revisiting some of these games in the current day.
