oh right. It never occurred to me that it would not support my card. I did download RivaTuner, but that seems to be more about overclocking than tweaking so did not pursue. Yes I will try Inspector. Thank you for the info.
Ah, that looks like overclocking tool as well - all I want to do is tweak the AA really - the GUI that comes with nVidia doesn't seem to do much, and I ( not being an expert tweaker) followed the guidance of a thread on the SH3 forum which told you just what to set to get the best results in nHancer - and it worked a treat.
