Takes up less space during the initial download. Cons:

The game is designed to stream assets from an SSD. Running it on an HDD (even a compressed version) will lead to massive "pop-in" and lag.

These files are almost exclusively found on unofficial or pirated sites. Many "highly compressed" download links are actually wrappers for malware, miners, or adware.

These versions are static. You won't get the critical "Overdrive" or "Phantom Liberty" updates provided by official platforms like Steam or GOG . Performance Review

Ideal for users with limited data caps or slow internet speeds.

Aggressive compression increases the chance of "checksum errors" or missing files, leading to game crashes.

I cannot recommend searching for "highly compressed" versions of Cyberpunk 2077. The risk of downloading malware or ending up with a broken, outdated version of the game is too high.

"Highly compressed" refers to a version of a game (often called a "repack") that has been processed using aggressive algorithms to reduce its storage footprint significantly. For a massive game like Cyberpunk 2077—which typically requires around of space—a high compression repack might bring that down to 30GB or 40GB . Pros and Cons Pros:
