Software updates

Imerge will automatically check for updates when launched, if your computer is connected to the internet. If it isn’t you can still easily check for updates manually to ensure you always have the latest features and tools at your disposal.

  • Auto-update: By default, the web helper that loads online help into the Projects page will check for any updates to the software when Imerge is launched. If an update is found, you will be notified in the Web Content column on the right side of the projects screen.
  • Dismissing updates: When notified of an update, you can either install it right away, or dismiss it until later. Click the Dismiss button that is displayed in the notification to suppress the update reminder for one week.
  • Updating manually: If you want to check for updates manually, you can do so at any time on our website. Just visit the What’s New page to see all the latest updates and what each one includes:

Notes on performance and large images (GPU)

Performance of Imerge can be optimized depending on your primary workflow. Editing images to adjust their color or tone relies on different system components that creating composites that combine elements of multiple images. So depending on whether you will primarily be editing or compositing, you can optimize your system accordingly.


  • Fast storage: Storing your images on an SSD or a fast HDD will ensure they can be opened quickly.
  • Lots of RAM: The more system RAM you have, the more quickly you can open large images or multiple images.
  • Fast CPU: The CPU is used to decode, or decompressed saved images so they can be displayed. A fast CPU will help images to open quickly.


  • Powerful GPU: For compositing, the most important system component is the GPU, which will process adjustments, masks, and other compositing tools as quickly as possible.
  • VRAM: Video RAM is a special type of ram built onto the GPU. Having more VRAM will provide better performance, and support larger image resolutions.
