Royal TS is using the Web Browser component shipped with Windows. By default the browser component will always use the IE7 rendering engine. 

To change the rendering engine, open the Plugins management dialog, select Web Page under Connection Types and click on Settings for the Web Page (based on Internet Explorer) plugin.

Older Versions:

In Royal TS 2.1.5 and earlier you can change the rendering engine for Royal TS by creating and setting a registry value according to the documentation ( link here ).

To control the IE version used to render content in Royal TS do the following:


In: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION
Add a new REG_DWORD value with the name: RTS2App.exe
The following values are supported:
9999 (0x270F)
Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive.
9000 (0x2328)
Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode.
8888 (0x22B8)

To adjust the rendering engine on a user level you can also use the following registry path:
