Because RVZ files use lossless compression, no actual game data, textures, or audio tracks are destroyed. When Dolphin loads an RVZ file, your computer or Android device decompresses the necessary game blocks instantly in the background. On any modern processor, this happens so fast that it introduces zero lag, frame drops, or audio stuttering.
Great for storage, but slightly less compressed than RVZ. 3. CISO (Compressed ISO) An older, common compression format. Pros: Fast to create.
