Battlefield 3 is a game I worked on during my 6-month internship at EA/DICE in Stockholm as part of the Frostbite team. Some of my tasks:

• Optimizing a dynamic water simulation for SPUs
• Implementing CPU based color grading on PC, Xbox 360 and PS3
• Optimizing light-probe selection for realtime radiocity on PS3
• Bugfixing in MLAA and other rendering code
