Its an unbelievably bad 'upgrade', it brings minor benefits over the Switch 1 version and some actual downgrades. - It runs at 30fps which is frankly unacceptable no matter what way you spin it. - 250ms of input lag that makes the game feel worse to play at 30fps than the original Switch version. - It's very clearly cheaply upscaled from 720p to 1080p in handheld mode using DLSS. I don't believe there's any ACTUAL resolution increase here. Given that there is theoretically a ton of headroom from it still being 30fps that is quite unacceptable. - The file size is a whopping 53gb somehow. Given that the PC install of the anniversary edition is only 19gb I can't help but feel there's a colossal mistake with the install here. I theorise that they've doubled up on the installed files, including an entire Switch 1 install as well as the Switch 2 version and all optional language packs. Given all this the Switch 2 upgrade is a colossal disappointment and a huge missed opportunity. I'd forgive it easier if it was a free upgrade to the base game but you have to pay £18 to upgrade to the anniversary edition. At least it adds back the volumetric effects from the special edition I guess? najlepsza wersja
