Bundle 2/NFS Hot Pursuit

From Burnout Wiki

Need for Speed Hot Pursuit uses version 3 of the Bundle format, adding support for an additional memory type, game changer IDs, and delta bundles.

Memory types[edit | edit source]

Across all Bundle versions, a common theme is the use of separate data chunks to define what memory type resources are loaded into. These chunks are as follows:

  1. Main Memory
  2. Graphics System
  3. Graphics Local
  4. Disposable

Keep these in mind when viewing the specs below.
