The graphical fidelity enthusiasts at Digital Foundry have taken a deep dive into the performance of the PC version of Sea of Thieves, and the results are pretty interesting ... and a bit frustrating for anyone who would like to play on the PC. You can watch the whole video above, and it’s an interesting look at the game.
Sea of Thieves is only available through the Windows Store, and is locked down in multiple ways to limit your control over the graphical options and even things like the language options and resolution.
