A modern blockbuster can occupy a fifth of a terabyte. The reasons are less about graphics than about how data is packaged and read.
Why installs grew
- Higher-resolution textures shipped in several variants.
- Audio in multiple languages, uncompressed.
- Duplicated assets to reduce seek times on mechanical drives.
- Cinematics stored as video rather than rendered.
Why loading did not improve proportionally
Faster drives help only if the engine streams assets rather than loading a level into memory. Many engines still assume a slow disk and duplicate data to hide it, which inflates size without improving load times on modern hardware.
What actually helps
Direct storage APIs, on-the-fly decompression on the GPU, and shipping language packs as optional downloads. The last one alone often saves tens of gigabytes.
What you can do
Install only the language you use, keep one large game per drive, and check whether the launcher supports partial installs. A 500GB drive is no longer enough for a two-game library.
Bottom line: the size problem is a packaging problem. Engines built for spinning disks are still setting the rules.
