Killzone Shadow Fall PlayStation 4 demo used only 3 GB of RAM

Killzone PlayStation 4

Developer Guerrilla Games recently published a lengthy tech paper on Killzone Shadow Fall, and in it, they revealed a bunch of PlayStation 4 details. Most surprisingly thought, Guerrilla revealed that the Killzone Shadow Fall demo that was showcased during the PlayStation 4 unveiling in February only used 3 GB of memory. The PlayStation 4 features 8 GB of GDDR5 RAM.

Killzone Shadow Fall characters feature 40,000 polygons, which is 4 times as many as characters found in Killzone 3. In the demo, 60 AI characters were present at the same time, with over 8,000 physics objects, 500 particle systems, 120 voices, and over 100 ray casts. All that was done with just 3 GB of memory and little optimization. This goes to show just what’s possible on the PlayStation 4.

Check out a technical presentation video below, showing some of the “behind the scenes” details on Killzone Shadow Fall on the PlayStation 4:

    It also goes to show that 8 gigs is way more than needed just for games at this time. Perhaps good future proofing but still unnecessary.

    I read that the PS4 only has 8GB of internal storage in gameinformer. Is this true?

    its like they are more focused on marketing the console than making the game

    Only? You’re forgetting that the RAM used for this one game is more than what’s available on full home consoles now.

  • The extra ram could be used to load more of the game. While playing a game the next level could be copied to ram. This will speed up load times. Remember that the operating system is using some of this ram. I’d rather have too much ram than not enough.

    This tells me the Wii U is quite capable of having games that will look very similar.

    On PS4, no games will ever use 7GB for graphics and stuff like that – it’ll be used for video-recording and cross game video chat and possibly some PS Vita compunication option.
