Quick answer: Multiply the per-second drain rate by Time.deltaTime, or accumulate elapsed time, so meters fall at the same real-world rate on any hardware.

Testers on fast monitors report they starve in minutes while 60 Hz players are fine. The hunger value is being subtracted per frame instead of per second.

How to fix it

1. Scale drain by deltaTime

Use hunger -= drainPerSecond * Time.deltaTime instead of subtracting a flat amount each frame. Per-frame subtraction ties survival pacing to refresh rate.

2. Or tick on a timer

Alternatively, decrement on a repeating timer (for example every real second) so the rate is independent of how many frames render in between.

3. Audit all survival meters

Apply the same fix to thirst, stamina, and temperature. These systems are usually copied from one another, so a per-frame bug in one often exists in all of them.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Unity error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

The bug you can't reproduce isn't gone — it's just invisible until you capture it from the player's device.
