For some reason my horrible little GT 430 is running a lot slower with this release (~20% less kh/s) and my computer is pretty much unusable while mining. Has anyone else been experiencing this? Anything I can do?

Edit: seems like a couple of people on reddit are having similar problems... it looks like mostly fermi devices. http://www.reddit.com/r/dogemining/comments/1wuvny/new_cudaminer_released_20140202_1020_increase_in/ (scroll down)

edit 2: http://poll.pollcode.com/7866812 seems more peoples hashrate decreased than increased as of now
