An attendee at our What’s New in Bluebeam Revu 2019 webinar asked us which of the three rendering engines is recommended for people who constantly deal with heavy PDF files. Thinking that other people may have this same question, we decided to provide the answer here.
 
This is the short answer: The hardware that comes out of the box. If you have trouble with that, you can choose the software or legacy rendering engine instead. 
 
Here are some details:
 
The “Hardware” option,  which is the default setting and recommended by Bluebeam, would be your best bet for large-scale, complex PDF files. But you can always try one of the others. 
 
Previously the default Rendering Engine for Revu used GDI (Graphics Device Interface). The GDI is a Microsoft Windows application programming interface and core operating system component responsible for representing graphical objects and transmitting them to output devices such as monitors and printers. However, it does not permit access to GPU (Graphics Processing Unit), which is your computer’s graphics card to allow for faster response.  
 
New in Revu 2019 is the Hardware Accelerated Rendering Engine. The new hardware-accelerated rendering engine provides improvements to speed and performance of panning and zooming in PDFs, improved performance and memory usage when working in multiple split screens and rendering preview of surrounding areas on a document. 
 
There are now three setting options for your Rendering Engine:  Hardware, Software and Legacy (GDI).

  • Hardware: The new Hardware option is the default setting “out of the box” and uses the SKIA Engine with GPU enabled. The SKIA Engine is an open-source 2D graphics library written in C++, used for Text, Geometrics and Images rendering. Using this allows you to gain access to your GPU (graphics card) in your computer.  This is the setting recommended by Bluebeam to best take advantage of the new hardware-accelerated rendering engine that provides significant improvements to speed and performance of panning and zooming in PDFs (up to six times faster), especially on those large format, complex line-drawing, vector files from your CAD programs that you work in everyday.  
     
  • Software: When you need more options for particular documents, there is now the second option, Software. It uses SKIA without the GPU enabled. This is a good fallback if your GPU isn’t working properly or if you are working in a virtual environment.
     
  • Legacy (GDI):  And then finally, we still have the good old Legacy (GDI).
If one rendering engine is not working to an acceptable level for a particular PDF, try switching to another to see if that resolves the issue!
