Common issues include lag, desynchronization between players, and glitches where one player sees a different game state than another.

How can developers improve cache coherence in their games?

Developers can use techniques like optimized data sharing, efficient memory management, and implementing robust synchronization protocols to enhance cache coherence.

Are there any games that have struggled with cache coherence?

Yes, many online multiplayer games have faced issues with cache coherence, leading to lag and desynchronization, especially in fast-paced environments.
