Being a Newb, I can't post this in the actual thread located here -
https://bitcointalk.org/index.php?topic=167229.0, so I thought I'd report my performance here and perhaps someone can post this to that thread for me.
Mining at stock clocks, I get 134-136KH/s with autotuning. This is about 10KH/s more than the fastest I could get on an openCL miner. With my Gainward GTX 570, the max temp is 63C with 51% fan speed.
Upon stopping the miner with ctrl-c, the graphics driver crashes and takes a few seconds to recover.
An option for specifying the intensity would be good to allow mining on a computer whilst still being able to use it without too much lag.
