I noticed two things while using / running the software over a day of, say, 8 to 10 hours: 1.) If I make changes it might come to a point where manually changing profiles takes around 5 seconds or more for them to load. I mean button profiles, with only a couple buttons remapped. 2.) If I don't make changes and just let the software run over the day, automatic profile change is delayed at the evening while it was changing fast at the morning. Like when I start a game and it instantly changes (I assigned different colors to my gaming profile) and later it can take up to a minute. As far as I can see the cpu utilization doesn't change much, it is very low, so is the memory usage, no problems there it seems.
