Dragon Quest X: Awakening of the Five Tribes Offline

running on rp5 (original edtion) with perfomance mode and max fan enabled. english translation enabled and working properly. (source: https://www.nexusmods.com/dragonquestxoffline/mods/2?tab=description) runs well in combat and outside areas but lags in cities and heavily populated areas. tested at 1x resolution - 0.75x runs about 2 frames better at the lowest but is generally more stable though models are really hard to parse in the chibi artstyle. not tested super thoroughly but was able to play about half of the intro sequence with no issues. not available options that are enabled: -enable host MMU Emulation -skip CPU inner invalidation -ASTC decoding method: cpu -fast gpu time: enabled, set gpu overclock to low (128)

The game itself might run smoothly, but there's a persistent texture bug in the graphics that won't go away no matter what settings I change. The houses in the first village and the entire town are constantly lit, making the game practically unplayable. If anyone knows how to fix this, please let me know.
