Bundle 2/Need for Speed Most Wanted
< Bundle 2
Memory types
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:
- Main Memory
- Graphics System
- Graphics Local
- Disposable
Keep these in mind when viewing the specs below.
