If you care about the health of your eyes and do not want to ruin your body’s internal sleep cycle, then you should be using f.lux – a smart software that can automatically adjust the temperature of your screen by adjusting the screen colors based on the time of the day. During the day it makes the screen brighter and displays more blue in the screen that helps you stay awake and alert. As soon as the Sun sets in your location, it slowly switches to warmer colors having more red in it in order to help you sleep better.
When using f.lux in your Windows 8.1 or Windows 10 computers, it harnesses the power of your GPU to get better quality transition to warmer colors as it night draws closer in your geographic location. If you are using f.lux on a small notebook computer or an older desktop computer that is not really very powerful then perhaps you do not want it to use your GPU power to reduce battery usage and improve overall responsiveness of the operating system.
Here is how you can lower GPU usage when using f.lux in your Windows PC:
- Right-click on the f.lux icon in the notification area.
- Select Options and Smart Lighting from the right-click menu.
- Select Features and Notifications tab in the options window that appears.
- Unselect the option Use GPU for better quality with very warm colors.
- Click on the Done button to close the options window.
If you are using f.lux In Windows 7 and earlier, then you may not find this option in the f.lux options. This is because f.lux does not use GPU in those versions of Windows and the option use GPU for warmer colors is turned off. In addition, this option is not available in the older versions of f.lux.
