Holy moly, I looked this up on Digital Foundry and provided the port's not a disaster, this could potentially be the most ambitious "impossible port" yet brought to Switch; it's 900/30fps with dips even on PS4 and just 1080p/30fps on PS4 Pro.
In terms of the specs, it's even more demanding than Witcher 3. I sure hope it's not another Ark situation; Saber Interactive have an impeccable track record on Switch so far but they've not tackled a game quite this demanding before and as we've seen recently with Apex Legends even good porting studios can stumble.
