Tips for improving performance | Revu 2018


  • Slow document rendering and refreshing when zooming and navigating.
  • Opening documents takes longer than usual.
  • Program becomes unresponsive.
  • Interface is slow to respond to input.


Some users may experience performance issues after upgrading to Revu 2018. The following are a set of potential solutions presented in order from least complicated to most complicated. Try them in order until the performance issues have been fixed.

1. 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.

  1. In Revu, click Revu > Preferences or press Ctrl+K.
  2. Click Advanced on the left. Make sure you are in the 2D Rendering tab.
  3. Select Wait for completion in the Rendering Mode dropdown menu and click OK.
How this helps
  • Reduces the total amount of time to redraw the PDF page by avoiding temporary redraws.
  • Reduces time to redraw the PDF page on 4K and high-resolution displays.

2. Change the Rendering Engine in Revu

Revu 2018 includes both a standard GDI rendering engine (on by default), as well as a new SKIA rendering engine. Each has its own strengths, so switching to the other engine may resolve your performance issue.

  1. In Revu, click Revu > Preferences , or press Ctrl+K.
  2. Click Advanced on the left. Make sure you are in the 2D Rendering tab.
  3. Select Advanced (Skia) in the Rendering Engine dropdown menu and click OK.
How this helps
  • The SKIA engine may be better suited to the file you are working with.

3. Change the power settings in Windows 10:

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 Power & sleep settings.
  2. Click Additional power settings, which will open the Power Options in the Control Panel.
  3. Click on Show additional plans to display the hidden plans.
  4. Select the High performance or Maximum performance setting.
How this helps
  • Improves display performance by increasing the resources Windows provides to the GPU.
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 Revu’s display performance.

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.

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

How this helps
  • Documents open faster.
  • General performance and responsiveness of program and interface performance.
