Pokémon Brilliant Diamond and Shining Pearl is out today on Nintendo Switch, but PC users can also play it on PC via the Ryujinx emulator. As with the most recent Switch releases like Monster Hunter Rise, The Legend of Zelda: Skyward Sword HD, Mario Party Superstars, and Shin Megami Tensei V, new exclusives on Nintendo's hybrid console easily run without major flaws on day one.

In the case of Pokémon Brilliant Diamond and Shining Pearl, the Ryujinx team touts no known graphical glitches, support for 60 FPS (even though NPCs will move faster than normal), and even the ability to trade and battle in multiplayer via LDN 2.4.
