iRacing uses a Content Delivery Network (CDN) to make downloads available to members. 


Choosing 'Cloudfront' or 'Limelight' will always download updates from that specific CDN.

The No Preference option will assign you to our preferred CDN when downloading.


If you are making this change due to downloads getting stuck or not starting, delete the contents of the \downloads\updates folder before restarting the download.


By default, this location is:


C:\Program Files (x86)\iRacing\downloads\updates


To change your CDN preference, follow the steps below.
