EVE Online testers on Singularity have already had a sampling of the DirectX 11 client, but other players will have a chance to try it out when it releases with the Rubicon expansion next month. Once the update goes live, players with an OS and GPU that supports DirectX 11 will have it automatically enabled while those that do not will continue to use the DirectX 9 client, but you can switch between the two if your system supports both versions. CCP also provided a brief list of answers for frequently asked questions in their latest dev blog.
EVE Online: Rubicon is scheduled to launch on November 18th, 2013.
