I've been using GrayFix for a while now, and gotta say, its UI is a major step up from Zonger66. The lag issues I had with the old app are almost non-existent on GrayFix. Definitely worth the switch in my opinion.
"Who else is loving the latest GrayFix update? Been running it on my GPU and I'm getting some solid gains in terms of mining efficiency. Anyone have any experience with the new pool integration?"
