A new Stranger of Paradise: Final Fantasy Origin workaround that has been shared online improves performance considerably at the cost of visual quality.

The new workaround has been shared on the PC Gaming subreddit by MorrisonGamer. The user created Shader Toggles with Special K that can disable visual elements like hair and fur, Soul Burst particles, and more that have a huge impact on performance. The downside is that the game will look even worse than it does, so the trade-off may not be worth it for some.
