How to install

Using the installer

Download the installer (flux-screensaver-setup-v*.exe). Open the installer and follow the instructions.

2. Right-click on the Flux.scr screensaver file.

3. Click Install.
   On Windows 11, if the Install option is missing, click Show More Options and then Install.

How to remove

If you used the installer

Select Start > Settings ⚙️ > Apps .

Select Flux from the list of applications and select Uninstall. Follow the instructions.

Manually

Find the Flux.scr file that you downloaded and installed. Delete the file and Flux should disappear from the screensaver options.

FAQ

• Q: How do I receive updates?

  A: New versions will be posted to Gumroad. You'll also receive an email with an announcement for big changes.

  If you don't have a Gumroad account, use the download link in your email receipt to access updates.

• Q: How do I change the colors/settings?

  A: Go to ⚙️ Settings > Personalization > Lock screen, and select Screen saver settings. Choose Flux from the drop-down list and select Settings to open the Flux settings windows.

• Q: Can I use Flux with Wallpaper Engine?

  A: Yes. Rename the Flux.scr file to Flux.exe and Wallpaper Engine should be able to run it.

• Q: The screensaver disables HDR on my monitor. What can I do to fix this?

  A: Use v1.5.0 or newer.

• Q: My antivirus says that Flux.scr is not safe. What do I do?

  A: This is a false-positive. You can safely whitelist Flux.scr in your antivirus software. Send me a message if this happens to you — I'd like to keep track of how often this happens.

• Q: Task Manager is showing really high GPU usage when the screensaver is running. This is way more than I expected!

  A: Most GPUs will significantly throttle down their clock speed whenever possible to reduce power consumption. GPU utilization reflects the load at the current clock speed, not the maximum clock speed. Tools like GPUZ can show you the clock speed, utilization, and power consumption of your GPU.
