Shortly after news came out that Playstation 3 Firmware 2.0 might be the cause behind Assassin's Creed frequent crashing, Sony released PS3 Firmware 2.01 update to fix the problem.
Playstation 3 Firmware 2.01 adds no new features, but instead it enhances the console's stability. The complete contents of the update are as follows:
- Stability during playing some PLAYSTATION 3 format software has been improved.
- Stability of System Software including Internet Browser and Information Board has been improved.
- Stability of the upscaler for PlayStation 2 format software has been improved. (Playability of PlayStation 2 depends on model)
- [Remote Start] feature is changed to avoid unintended power on.
Unfortunately, the new Firmware is currently suspected to have broken Call of Duty 4's multiplayer. As usual, there is no official comment from Sony nor Activision yet, but dozens of angry fans reported and confirmed the problem on the game's official forum.
