# Loading and downloaded files — NFSU2 Browser

Understand streamed resources and first-start loading.

## What loads first
The approximately 35.5 MB WebAssembly engine is compiled after Play. Browser transfer compression can reduce network bytes. Worker code, graphics and the first scene follow.

## Data arrives as needed
English resources without movies total approximately 1.98 GB. The player downloads one-megabyte blocks as the game reads its files. Later cars and tracks may require additional downloads. Movies are disabled in this version.

## Cache and retry
Downloaded blocks stay in the browser’s file storage. Keep the tab visible during loading and read any error message. Cancel removes the active runtime; a later retry creates a clean instance.

## Clear downloads safely
Quit the game before clearing downloaded files in Player options. The download cache is separate from saves. Clearing all browser site data removes both.
