Metro: Last Light has been a hit for developer 4A Games, and they put together an impressive game that looks and plays fantastically on current-gen technology, which is amazing given the circumstances that the game was made in. 4A Game's Oles Shishkovstov sat down with Eurogamer to discuss the technical aspects of Metro: Last Light, and the subject of the PlayStation 4's specs came up. On his thoughts about the console, he said:
"I am very excited about both CPU and GPU. Jaguar is a pretty well-balanced out-of-order core and there are eight of them inside. I always wanted a lot of relatively-low-power cores instead of single super-high-performance one, because it's easier to simply parallelise something instead of changing core-algorithms or chasing every cycle inside critical code segment (not that we don't do that, but very often we can avoid it)."
On the PlayStation 4's 8GB of RAM, Shishkovstov gave his two cents on the massive power that the RAM can provide.
"RAM is really, really important for games, but all of it actually being useful depends on available CPU-side bandwidth and latency to the external storage device. I think that they put slightly more RAM than necessary for truly next-generation games this time, but considering the past history of Sony stealing significant percentage of RAM from developers for OS needs - that may be exactly the right amount!"
Shishkovstov also gave his hopes for the next-gen consoles, including more realistic characters in future games.
"It seems that personally we will jump to next-gen rather sooner than later. We are currently focused on another important aspect of our games - characters. I mean we are not only working on believable appearance/visualisation, but also are in deep research on believable motion and animation. In a nutshell that's full-time physical simulation of the entire body with generated animations based on a "style" model learned from motion capture."
