The details shared here apply to the most recent version of Turbo. To keep your theme up to date, check out this helpful document.
Our premium Shopify theme, Turbo, is built and optimized for speed. With this, the theme includes a performance setting where there are two options to choose from: Ludicrous and Sport.
This setting is located in your Theme Editor (customize) under > Theme Settings > Performance.
When set to "Ludicrous," you get the full advantage of all of Turbo's performance-enhancing features.
However, certain third-party apps or custom code may experience technical difficulties with the "Ludicrous" mode.
Because of this, we offer "Sport" mode.
"Sport" mode offers all of the same performance enhancing techniques used in "Ludicrous" with only a single exception — page preloading.
In Turbo's Ludicrous mode, page preloading uses advanced methods to attempt to predict the next page the user will visit. If it is able to determine this, it starts loading that page in the background, so that if and when the user does click the link, the page will already be partially or, depending on a variety of factors, completely loaded.
The reason "Sport" is needed is that some apps are not compatible with this page preloading technology or the apps require a full page load rather than it being loaded in the background.
If you're experiencing issues with Turbo and have apps installed on your store, we suggest switching to "Sport" and seeing if that helps.
Of course, it's always possible that, like with any theme, "Sport" mode may still have conflicts with apps. In this case, we suggest disabling the app or working with the app developer to resolve the issue.
