I donīt know what you use, and most controllers today are USB, which should guarantee a smooth performance.
However, a bugged driver can cause that.

I had a usb printer at work, that, when plugged in, it would ear about 80% of cpu ,without being used.

I would try to disconnect every single non-necessary thing.
Like, controllers, cameras, pen drives, printers anything that might be started when DOSBOX starts.

My bet would be a faulty controller driver.

I guess itīs worth the shot.

Also, what soundcard do you use?
Try swtiching between ASIO and WDM drivers.
For my SB, it has to be ASIO, otherwise, performance is shit. (but since i use my pc to record, soundcard performance is big to me).
