Can someone explain or link me to a tutorial on displacement? I thought that it was essentially supposed to be a better looking nor map technique that actually moved vertices to preserve real shadows and what not. However, whenever I try NOR maps, they work fine. But if I try displacement maps, I get a horribly jumped mess of geometries all over the screen that look nothing like the NOR results I had just obtained.
Anyone use DISP? Any help?

Make sure your Nor slider is at 0.00 when using Disp.

Very cool. Got it working. I also needed that info about using the subsurf at render time but not during edit mode. The subdiv would have brought my PC to its knees without that tip. 
Thanks for the tips and tut
Only oddness I saw was in the SizeX, SizeY, SizeZ options on the texture. I had to se those numbers way up (20, 20, 20) to get the exact same result as I did with the NOR map (at 4, 4, 4). Not sure why that was. But the final result was SOOOO much better than nor mapping.
