I'm glad that it looks like Metaphor ReFantazio will give me an upscaled PS4 game with the choice of bad performance at a high resolution (PC) or consistently mid performance and awful aliasing (PS5), both with terrible motion blur while sprinting.

The motion blur is easily the worst part and I really, really hope you'll be able to turn it off. Frankly, the possibility of a mod to disable it might push me towards PC even if performance stays worse. It's really bad.
