The term "highly compressed" is often used in a misleading context online. Users should distinguish between technical file optimization and deceptive "rips": The term "highly compressed" is often used in
: On a modern, mid-to-high-range CPU (e.g., Intel Core i5 or AMD Ryzen 5 series or better), the performance impact of compression is negligible for the majority of titles. The overhead is small. However, on low-power devices like older laptops or mini-PCs using CSO or GZIP might provide a smoother experience than CHD, as they are less demanding to decompress. However, on low-power devices like older laptops or
