Unreal Engine 5: Tim Sweeney clarifies about the framerate debate on PS5

    Unreal Engine 5: Tim Sweeney clarifies about the framerate debate on PS5

    An intense debate has been going on for days now, which sees the much discussed tech demo of theU presented on a PlayStation 5 just over a week ago. More specifically, the latter was shown at a resolution of 1440p and with a framerate of 30fps constant, however, a Chinese Epic Games employee later managed to demonstrate that the Unreal Engine 5 demo on his notebook reached the resolution of 1440p e 40fps, thus winning 10fps more than the version shown on PS5.



    From here, an avalanche of controversy literally started and, subsequently, the CEO of Epic Games Tim Sweeney denied and denied all this by answering the multiple questions received from users via the Twitter platform. In the last few hours, however, new statements have arrived in this sense and Sweeney in this case spoke in a decidedly more concrete way, going into more detail and arguing that in the PS5 demo a fixed block at 30fps was voluntarily inserted with the Vsync simply to allow for more uniform execution:

    To achieve a 30% solid 100fps framerate with Vsync in the demo, the times per frame vary from 30fps and up. All the hardware of the next-gen consoles have not yet been launched and are under NDA (non-disclosure agreement): at the beginning of 2021 we will launch a public version of the Unreal Engine with the source code complete and open to anyone, so everyone can go through it in detail.


    Not sure exactly what was said. The translated quote on 40 fps isn't a comparison between hardware capabilities. To hit a 100% solid 30 fps with vsync in the demo, per-frame times vary from 30 fps up to much higher.
