That's a slightly different command from the one earlier, which had quality setting inside the <>. Wonder if they both work or if one is better than the other?
I guess this means when I DL the game onto my PC, I'd better know how to do this because I'm betting the patches DL automatically too. 
He's referencing this post by Conal Pierse: http://forum.bioware...9#entry18031083 This is the super important part though:
It’s also important to note that pre-patch 2, all users on PC were being forced to use the Ultra shader quality. This means that those of you playing on lower settings will notice a decrease in quality, particularly players using low or medium settings.
To achieve the same visuals as pre-patch, users on lower settings will need to change their settings to Ultra, which should likewise be used in conjunction with Ultra mesh quality. Mismatching the mesh and shader settings will result in other visual artifacts like overly shiny hair.
So, set it to Ultra and make sure your Mesh settings are on Ultra too. (I think?)
