Should be getting closer to 200 than 100 with your card.  Try using these parameters on that chart according to your vid card

My card isn't on the list, it is an MSI brand GTX660Ti. I have tried putting the settings for the similar GTX660Ti cards but the .bat file always fails, this ofcourse could be me putting the switches in the wrong place 

. I am using speccy to see what my card is, can't match it to any of the other specs(numbers) that don't have a physical brand after them on that list
