Works exactly as advertised. Cut my CPU and GPU utilization a substantial amount. I'm using it with ISBoxer and I actually adjusted my FPS limits higher for both fore and background in that CPU strategy wizard. Then using this I've set my background to 2 fps so I can still get an idea what those characters are doing on my 2nd monitor. With 6 chars running before I'd be close to 100% CPU on my 6-core FX-6300. Now I'm running about 50% with all 6 instances running Kiss 11.008 and I'm actively pulling mobs. There is one thing to get used to, when running in the background all you see is the base picture without any text boxes. It's more like watching a movie in full screen mode.
