Ryujinx | Pokémon Scarlet | 5800X | RX 6600 | Native | 2023

Ryujinx 1.1.592. Native resolution with many flickering/missing textures. Tested on a Ryzen 7 5800X and RX 6600 8GB. Enjoy!

Ryujinx did not want to load the game beyond native resolution. As of this build, this seems to be AMD specific. However, additional upscaling can be achieved using Lossless Scaling.
