Just change the references to League of Legends to Dragon Age in your head. If this is not clear enough, there's a more detailed guide on this League of Legends forum. Then make sure the 'high performance NVIDIA processor' is used as its default device.
Open the Nvidia control panel, go to 'manage 3D settings', open the 'program settings' tab and select Dragon Age Origins from the list (or add it to the list by browsing for the executable file). This doesn't always happen, however, which means you sometimes play games on integrated graphics instead of your dedicated graphics card. Some PCs (mostly laptops) will use the Intel chipset most of the time to save power, then switch to the Nvidia GPU when you launch a game. I also see in your dxdiag that you have both a dedicated Nvidia graphics card and an integrated Intel chipset. It provides options to different body types for slightly different profiles, smaller hands, and options to change the body hair. This mod complete updates the bodies types for several characters. That way you know which mod is causing the issue. Dao Natural Bodies Dragon Age: Origins - Realistic Nudes. If you have more than one mod, you can start reactivating them to see if the issue returns.
Do you get the issue only when wearing a mod outfit, or on all armor? In any case, try temporarily disabling mods to see if the issue goes away.
