Since at least this year’s E3, if not before, it has been clear that the usual market cycle of clearly delineated console generations is being upended. The new model—as exemplified by Sony’s PS4 Pro, Microsoft’s upcoming Project Scorpio, and even last year’s “new Nintendo 3DS”—sees a single generation of console software working on multiple tiers of hardware power, with consumers deciding where exactly they want to sit on the price/power continuum.

The idea, as pitched, is that the cheaper, lower-end hardware will still provide an “acceptable” experience, while the more expensive high-end hardware makes everything look and perform just a bit better. Already, though, we’re seeing cases where games seemingly tailored for high-end console hardware are struggling to provide bare-bones performance on legacy hardware.

Last week’s release of The Last Guardian—coming nearly a decade after the game was first started as a PS3 title—is one of the highest profile examples of this problem. As Digital Foundry notes in its analysis of the game, “if you’re on a regular PS4 you’re in for a very variable experience; lurching between 20-30fps just by running around empty areas, and with stutters to over 110ms.” The analysis goes on to call the stock version of the game “way off the pace compared to what we’ve come to expect from a modern PS4 title.”
