Pcsx2 Games Highly Compressed Work ^new^ 💯 Limited Time

Ratchet & Clank and Jak and Daxter are surprisingly compressible once the padding is removed.

On modern PCs, the CPU overhead required to decompress a CHD or CSO file is negligible. You likely won't notice a frame rate drop. However, on very weak hardware (like budget handhelds), high compression can cause micro-stuttering during data-heavy scenes.

PCSX2 supports the .CSO format natively. You do not need to extract a CSO file to play it; simply load it as you would an ISO. However, there are pros and cons to using compressed formats:

Using tools to compress standard ISOs into formats like .chd (Compressed Hunks of Data) is incredibly effective. Many users on Reddit's r/PCSX2 report saving 30–60% of storage space without losing data, which is essential if you have a massive library.

The primary benefit is massive space savings. Highly compressible games (those with lots of "null" data or repetitive textures) see the most benefit. For example, a game like LEGO Star Wars might shrink by 60%, while a movie-heavy game like Final Fantasy X will shrink much less.
