Some minor issues

I'm having some minor frame rate issues with Bandicam, everything is going fine it runs at well over 60 fps, then when i hit record I drop to 30 or so 40ish being the highest... I've never been one to favor low quality, and have found myself put off by video's i go to watch that are of low quality. If anyone can offer any advice on how to fix this issue that will be great. Until i can i won't put out any videos... I hate putting out crap content...
