Star Ocean: First Departure

[[Unknown]]

Yes, the game uses buffers when it does the stencil test. Disabling the game's buffers will prevent it from working.

What device are you using?

If it's slow even with stencil testing disabled, then it's probably related to other settings. Some settings that could cause problems / slowness:

1. Render resolution, depending on the device. Try 1x and see if it's still slow. For example, even on a relatively powerful desktop, 6x is less than half the speed of 1x. This will be much worse on mobile, since 6x takes 36x as much work compared to 1x.
2. Display resolution on an Android device. Try 1x also.
3. Texture scaling, on any device. Try off. Anything above 3x is probably massive overkill and may cause slowdowns in various games even on a powerful desktop.
4. Retain changed textures may make this game slower.
5. Any customized (non-default) cpu speed could theoretically cause problems.
6. Multithreaded can make this game faster but not sure if it becomes unstable.
7. Enabling rewind snapshots (System settings) will make pretty much any game get progressively slower on weaker devices.

Is it only transitions that are slow, or whenever panning the screen?
