UPDATE: Emma Matthews and Christian Vaz attended the recent PC Gamer Weekender event in London for GameWatcher, and both have confirmed that the PC version of Dark Souls III was locked at 30FPS, although we're still unsure if this is because it's an early press preview build. It might be that the final version will remove that lock, but we'll hopefully have this confirmed shortly.
Original Story: Let's take this with a pinch of salt at the moment, because it's currently unconfirmed, but according to Bandai Namco's online store support, the PC version of Dark Souls 3 will be locked at 30FPS.
"Unfortunately the plan is to keep the frame rate locked at 30FPS, but nothing has been confirmed from what I am aware yet" said the Bandai Namco Store representative in ato a question from a user on reddit called khawaja07.
We've requested a statement from Bandai Namco's PR team here in the UK, although it's likely that we'll hear anything until tomorrow morning as we're now out of work hours. Still, it's hard to believe that Dark Souls 3 will be locked at 30FPS. Dark Souls 2 was able to achieve 60FPS when it was released for the PC back in April 2014.
We'll keep you posted.
