ARVee,
I don't have a 660Ti.
But,,,,,,,,
I think you are doing a great job! lol!!!!!!!!!
I am having a bit of problem understanding why the version of Precision doesn't have a slider on the main -page for either the processor cores or shaders, whichever they want to call it.
One idea is that you can go into the tools of the Precision Tuner and select which tools and charts appear on the main page.
Maybe the shaders or processors is one of them....Just a thought....
