Improving emulator performance on Android often comes down to matching the right emulator with correct settings and files. PPSSPP runs best when resolution scaling is kept reasonable, frameskip is adjusted carefully, and background apps are limited, but when moving to PS2 emulation, AetherSX2 is usually the stronger option on capable devices. One detail that often gets overlooked is the BIOS setup, because a properly configured
bios aethersx2 can improve compatibility and reduce crashes in certain games. Pairing that with Vulkan rendering, safe speed hacks, and per game tweaks can noticeably reduce lag. Other PS2 emulators exist, but results vary widely, so focusing on correct configuration and device limits matters more than switching apps constantly.
