Game mode

Your game first.

When a game starts, RAM Optimizer:

  1. Puts background apps last in line for memory.
  2. Frees idle apps once.
  3. Closes the apps you picked.
  4. Puts everything back when you quit.

It never closes anything you didn't pick.

How it works

No fake boosts

Cached RAM is good

Windows keeps spare memory as cache. We count it as available.

In useCachedFree

No constant trimming

Freeing the same apps over and over causes stutter. We don't do it.

Closing is the real fix

Closing an app frees its memory for good. We make that easy and safe.

Safe updates

Every update is signed. Fakes are rejected.
