Digital Foundry reports that the Final Fantasy 15 Trial of the Titan demo from E3 reveals a much more solid frame rate over the previous playable demos.
The tech blog states the demo manages a near stable 30 frames per second, a big improvement compared to the drastic drops in performance in the Episode Duscae and Platinum demos.
Whilst PS4 and Xbox One versions are both targeting 30 frames per second, game director Hajime Tabata confirmed to Gematsu that there is a big difference in each game's resolution.
"For the Xbox One E3 demo, dynamic resolution ranges between 800p to 900p, usually closer to the 900p range, and at a constant 30 frames per second," Tabata says. "So it is performing at a more stable and higher level than Episode Duscae and the Platinum Demo. There are times when it still dips, and that's usually when you call on your ally commands, like when you call on Ignis to mark an enemy it dips to 26 to 27 frames, but it won't deter from the experience. But since we're able to achieve this for the E3 demo, we have a positive outlook on the final version of the game."
Regarding PS4 he added: "For the PlayStation 4 E3 demo, it's a dynamic range between 900p and 1080p. Most of the time, it's about 1080p at a constant 30 frames per second. Sometimes, it will, just like Xbox One, dip a little bit when the GPU can't process what's happening on the screen so quickly, but it's mostly 30 frames. But we will continue to fine-tune and optimise the game for as much time as we can."
Comments made by Xbox boss Phil Spencer last week also indicate the game's resolution scaling will be able to max out at a steady 1080p when playing on Xbox One Project Scorpio. Sony hasn't explained how games would utilise the extra power of PS4 Neo.
