Hi, been having this problem since a couple of Windows 10 updates ago, use to work just fine and does work fine on my other, slower PCs. I play in Windowed mode and when I do something else, like look at email or a browser or even just click on the desktop, and then make the DDO window active, DDO will hang for about 2 to 3 seconds. I tried changing resolution of the DDO client, the graphics quality, updated the graphics drivers. Changed to DirectX 11, 10 & 9. Nothing I tried seems to work. Any Suggestions?
