What Reddit users keep repeating.

"Save in-game regularly. Save-state undo is disabled by default on Android, and overwriting a slot on the main menu can brick your session."

"Multithreaded (experimental) often slows games instead of helping. Leave it off. I/O on thread helps when storage goes to sleep mid-session (Project Diva lag)."

"If Vulkan stretches or black-screens on older Android, OpenGL is the safe fallback. Test one backend change before touching resolution."

"Convert ISO → CSO with maxcso to save 40–60% space. Use lower compression for action-heavy games; max compression can stutter on weak hardware."

"Disabling Fast Memory fixes some multiplayer games, but if you need it off for single-player too, that's a bug worth reporting on GitHub."

"Texture scaling is a speed killer on budget phones. Anisotropic filtering is nearly free on modern GPUs. Use that instead for sharper distant textures."
