The main screen of the advanced control shows an estimated TPF, which is to my understanding the time it takes to complete 1%. For my GPU it bounces from upper 14mins to lower 10mins. It does NOT fluctuate between them, never at 11 or 12, it is one or the other. This caused me to back off my OC because I thought something was fishy, but it does it even at stock clocks...
I know it could change depending on PC load, but I've gone to the log files and personally calculated the time between completed % and it is a LOT more stable. Varying from 00:12:17 to 00:12:26 and fluctuating with a few times in between.
It's really no big deal, but I would like a better approximation since it uses that to calculate the ETA of the completed WU. With its horrible estimations, it can end up being 3 hours off! If there is a way to fix this, I would greatly appreciate it.
Well, back to overclocking now and I will keep my eye on the logs to see if I get any gains
