Ni no Kuni: Wrath of the White Witch [BLES01555]

Which version are you running?

I've been using the latest version and regularly updating since the 0.0.5-7500's. Default settings, Vulkan is faster but prone to crash with the unknown magnify filter error if you can't keep a perfect 30 FPS, and OpenGL is a little slower but more stable.

Yeah, illynir finished it a couple days ago with no major issues, i played it for a 15 hours too. It's honestly probably playable now.
@Scale You can find people's version settings etc in their log files. But just use the latest build of RPCS3, there's no need to use anything older.

Yeah, I have about 25 hours of playtime now (past Phil's Nightmare) with barely any crashes in OpenGL. Vulkan isn't quite as stable (sometimes has unknown magnify filter and GFX FIFO RET without CALL crashes) but is mostly reliable as well, and a bit faster.
