Short answer

Updated Oct 8, 2026

On a PC with two graphics chips, Windows chooses one per program. A game that ends up on the integrated chip runs far below what the PC can do. Windows stores the choice per program as GpuPreference, where 2 means high performance. This tweak sets that for every installed game the app finds.

What it does

In the app the switch is called "Run Installed Games on the Fast GPU", described there as: Sets every installed game the app finds to the high performance graphics card, for laptops and PCs with two graphics chips.

When it helps, and when it hurts

When it helps

Gaming laptops and desktops with integrated graphics enabled, when a game runs on the wrong chip.

When it hurts

On a laptop the dedicated chip uses more battery, which is what you want for a game but not for a light one.
On a PC with a single graphics chip it changes nothing.

What it writes

Exactly what the switch changes, read from the app's source. Switching it off is what the app writes when you turn the tweak off again.

This tweak has no fixed list of registry values to print here: it works through a driver's own settings, scheduled tasks or values that differ from PC to PC (per device, per adapter or per installed game). The app reads what your PC has and changes only that.

How to undo it

In the app: Yes

Switching it off puts each game's graphics preference back as it was, or removes it when there was none.

Switch the tweak off in Frozen Tweaks.

Changing several settings at once? The app's Make a restore point button, on every plan, makes a Windows restore point before you start.

Verdict

Recommended on any laptop with two graphics chips. It fixes one of the most common causes of unexpectedly low FPS.
