Microsoft Windows has a feature whereby you can run any application or program in Low, Normal or High priority. By default most programs run in Normal priority including Revit. Now the idea is to run Revit in High priority to ensure that Revit runs as fast as possible.

There is an easy way to set the application priorities which I’ll describe in this article and then another way where you create a batch file that starts Revit in High priority.

First start Revit. Once you have started Revit right click on the Task Bar at the bottom of your screen. And click ‘Start Task Manager’.

Windows Task Manager

Within the windows Task Manager click the Processes tab and search for Revit.exe. I quick way is the simply type r (for Revit) on your keyboard and the selection will jump to the first process that starts with r – in this case Revit.

Select Revit.exe. Right click on Revit and set priority to high.

However, I need to state that changing the setting does warn the user that it may cause instability in the system.

Revit will now run in High Priority mode. This means Windows will give priority to the calculations needed to finish tasks inside Revit before calculations in other applications like Outlook etc.

As an example I rendered a view called Approach from the sample Revit project in medium quality.

Revit Project in Medium Quality

The average time it took to finish rendering the view on normal priority was 1m50s (I rendered the view three times.) After restarting Revit and setting the priority to high, I re-rendered the same view three times. This time the average was 1m47s. So indeed quicker.
