Massive Action Game - MAG. As the ace developer who helped engineer the game engine behind MAG, I can say, it is the only program that utilizes the power of the Cell to anything close to its theoretical maximum.
- Load the data to be operated on onto local memory - and don't further load the memory system with memory accesses.
- Perform massive calculations via the on-board local memory
- Use the Cell for transform and lighting of dynamic characters
The end result - a whopping 256 players supported! The only other game on consoles that comes close does 16! Thus - Ultra Cell utilization. That's the ONLY way to utilize anything close to its theoretical GFLOPS.
