You can try reducing latency with Edit → Preferences → Recording → Audio To Buffer. A bigger buffer helps to prevent “glitches”, but it adds delay.
You may have to use a different hardware setup that allows you bypass the computer and monitor yourself directly. [u]Here[/u] is a similar discussion that may be helpful.
Or, you can try Googling “Reduce Audio Latency”. There are LOTS of things you can try, and many people do get acceptable latency while monitoring throgh the computer. (Sometimes it requres “pro” hardware & software with ASIO drivers.)
