The decompression process is computationally expensive. A legitimate FH5 installation takes ~20 minutes on an NVMe drive. An HC repack installation can take on mid-range CPUs (e.g., Intel i5-9400F), with CPU temperatures often peaking at 85–90°C. This trades bandwidth for time and thermal stress—a critical factor for laptop users.
