Loading Levels In Crysis 2
Loading a level is actually more storage-intensive than launching the game. This makes sense, since you aren't loading lots of graphics data until you start playing the game itself.
|Overall Statistics||Crysis 2: Level Loading|
|Read Operations||9 493|
|Data Read||755.01 MB|
|Data Written||26.49 MB|
|Disk Busy Time||2.27 s|
|Average Data Rate||345.00 MB/s|
When we load the last level in Crysis 2 (A Walk in the Park), our Vertex 3 has to read more than three-quarters of a gigabyte. Almost all of the operations are sequential in nature, but the majority of them occur at a 128 KB transfer size. That's a large enough chunk of data that there's no bottleneck imposed by little tiny transfers, as there was before. In short, you'll see a substantial speed-up loading a level on a SSD compared to a hard drive.
- 46% of all operations are 128 KB in transfer size
- 50% of all operations occur at a queue depth of one
- 15% of all operations occur at a queue depth of two
- 10% of all operations occur at a queue depth of three
- 75% of all operations are sequential
