The original ARK Survival Evolved on Nintendo Switch was a complete mess and throughly unoptimised for the platform. The team recognise this and have been working with a third party to revamp the overall experience for Nintendo Switch owners with new and improved visuals, a better frame rate, resolution, plus a host of other changes. If you own the original ARK game on Switch you can download the new and improved experience for free, which sort of makes up for the terrible original. There is only one bit of bad news as the multiplayer servers aren’t live. The team says that a patch for this is in submission with Nintendo and they are just awaiting approval from the company. To make up for the lost time there will be multiple boosted rate weekends when the patch goes live. You can give the game a whirl here.
