I am having constant issues with this game running in DX10. Some times I can't even log in because it closes before the Turbine logo even starts. It was directly related to DX10 settings as it WILL load normally if the client is placed in Compatibility Mode for XP SP2. Afterwards the starting the client in compatibility mode, close it down, turning off compatibility mode, the client will start and give the DX10 options and require a restart. When the machine is restarted with DX10 active it's a consistent rinse and repeat of the headache with no fix other then pure randomness to even start.

Please give me an adequet and detailed walkthrough how Turbine supports and requires the setting up of this for a user with Vista 64 sp1 and a 4870x2. My machine is completely up to date although I suspect the game client it not.
