Does adding more CPU cores always improve game performance?

Not automatically. A game only benefits from extra cores if its code is actually written to run work across multiple threads at once.

Why might a game run fine on a powerful PC but stutter on a slower device?

It usually comes down to which resource is the bottleneck. A powerful PC often has enough headroom to absorb inefficient code that exposes itself as a bottleneck on slower hardware.

Coordinated Universal Time (UTC)

What is UTC?

UTC, or Coordinated Universal Time, is the global time standard used to synchronize operations across time zones, critical for keeping networked applications and services consistent across multiple servers worldwide.

UTC succeeded Greenwich Mean Time (GMT) and gives developers a universal reference point that isn't affected by daylight saving time adjustments.

How is UTC used?

This standardization is especially valuable for multiplayer applications and distributed systems that need precise timing coordination across geographic boundaries, the kind of synchronization Unity's own multiplayer solutions are built to handle.

For time-sensitive features like scheduled events, server maintenance windows, or transaction timestamps, UTC offers a reliable foundation that prevents confusion or desynchronization issues. Development platforms typically provide built-in functions to convert between local time zones and UTC, so an application can display a user-friendly local time to each player while keeping one consistent internal time reference for all system operations and data records.
