Basically I have no lag unless I'm doing 25m raids at which point I start to lag. Fights which are graphic intensive lag me considerable to where I have problems keeping up with mechanics. I have all setings at fair or lower. I'm not too sure what to do to reduce lag. I have the same issue regardless of if I'm using d3d9 or opengl.
I have a gtx 660, a amd fx 6100 6 core processor x 3, 16gb of ram and I'm using mint 16.
