Issue Details:

With DX-11 enabled in Lord of the Rings Online all of my system memory (8Gb) is gradually consumed and then the pagefile is gradually filled until the game stops. The game doesn't crash or freeze I just can't move my character for a few seconds. I also run Guild Wars 2 and don't have the issue in that game but there also is no option to enable or disable DX-11 in that game as there is in Lord of the Rings Online.
