Nice idea!I built the latest version of Ryujinx Vulkan and the game works fine for me. Steady 30fps, no memory leak and only crashed once in 3 hours. Seems to be much better than last week.
I'm doing all side quests on chapter 3 using latest Ryujinx Vulkan, 4h+ of gameplay already with this build. It's very easy to build.
I want to use Ryujinx because it has better visual fidelity right now. Yuzu has missing particles. Yuzu Vulkan also has other problems, like waterfall with shiny golden water during a hero quest.
One tip for screenshots:
I mapped LS button to emulator screenshot button to take screenshots. If someone are interested, AntiMicroX is opensource.
