Why is KNLMeansCL slowing me down so much

I'll have to try those steps tomorrow. I left the other setting at 2=quicksync during the KNL test. But in the meantime, what would cause those things to stop working if they were working to begin with? Because like I said, I used to use KNL and still get over 3fps and then it suddenly doesn't do that anymore.
