This feature already exists. It's called "throttle" in the configuration files. throttle=10 will pause for 10ms after each iteration. You obtain a noticeable slowdown, and your "idle cpu" will be at 80% (well, depending on your machine and ms). I use it for a different reason: the heat of the power brick on my laptop it quite noticeable. By adding the throttle, it can no longer fry eggs. I would love to see throttle moved onto one of the main configuration screens in the software; as opposed to its current buried in undoc.txt status. There are other "be nice" items in undoc.txt too, such as "don't run when program X runs." so, your "IMHO" is more than an opinion, it's a feature. :-) -j _______________________________________________ Prime mailing list [email protected] http://hogranch.com/mailman/listinfo/prime
