We've done a lot of work optimizing the game for different CPUs and GPUs, as well as adding a lot of different graphics customization options," Takai explained. "We've also added support for various upscaling technologies, such as NVIDIA DLSS3, AMD FSR, and Intel XeSS, and increased the frame rate cap, too."
Takai also revealed that PC users wielding PS5 DualSense controllers will be able to enjoy full-fat haptic feedback, too. However, the game has also been optimized for those who are rocking it old school with a mouse and keyboard, too.
"There are plenty of other options I haven't mentioned, so I hope you enjoy playing around with them!"
He further adds:
"It was always our aim with the PC version to make it playable for as wide a range as devices as possible, and that includes the Steam Deck."

Regarding XBOX
"We're taking one thing at a time right now, so I can't reveal anything about our future plans. All I can say is, it's something I would personally like to see happen!"
