Tips for improving performance

Applies to:

  • Revu 21
  • Revu 20

Problem

  • Documents render and refresh slowly when zooming and navigating.
  • Documents take longer than usual to open.
  • Program becomes unresponsive.
  • Interface is slow to respond to input.

Solutions

1. Change the rendering engine in Revu

Revu has multiple rendering engine options. Hardware rendering generally works best, especially if you have a dedicated graphics card. To get started, follow these steps:

  1. Go to Revu > Preferences (Ctrl+K).
  2. In the Preferences sidebar, select Advanced.
  3. On the 2D Rendering tab, from the Rendering Engine dropdown menu, select Hardware, and then select OK.
    4. If you are experiencing issues with hardware rendering, try switching to Software instead.

2. Change the Rendering Mode in Revu

The Wait for Completion rendering mode disables partial redrawing of the display. Instead, the screen will not update until the full page is ready to display. This will reduce the total redraw time for the PDF, especially for 4k displays.

  1. Go to Revu > Preferences (Ctrl+K).
  2. In the Preferences sidebar, select Advanced.
  3. On the 2D Rendering tab, from the Rendering Mode dropdown menu, select Wait for completion, and then select OK.

3. Change the power settings in Windows

Aggressive power saving settings sacrifice display performance in order to reduce power consumption and extend battery life. They affect both laptops and desktops.

  1. Click Start, type power settings, and select Choose a power plan.
  2. Select the High performance or Maximum performance setting.
If you're using a laptop, this change will reduce your battery life. You may want to return to your original settings if this doesn't improve your performance in Revu.

4. Update the Microsoft Visual C++ Redistributable:

Install the latest version of the Microsoft Visual C++ Redistributable. These updates will improve rendering performance for large images and scans within Revu.

5. Update the Microsoft .NET Framework

Install the latest Microsoft .NET Framework that your PC can work with. Click here to find which Windows version you're running, and then check this page to find the latest version of .NET that your version of Windows supports.

Save your work and close all programs before starting the installation. A restart of Windows is often required when the installation completes and you should restart even if you're not prompted to do so.

Once the .NET installation is complete, documents will open faster and the general performance and responsiveness of the program will improve.

The .NET Framework installation will take a few minutes to complete.
