I was wondering if the couple second slowdown in a Windows game I like (Zuma) that occurs every few minutes, is due to Windows Processes briefly taking up some of the CPU. Do processes such as jqs.exe continue during a game - I can see by viewing the task manager (while doing no processing) that jqs jumps to 10% from time to time, very briefly. I turn off my Avast anti virus (and see that the latest version has a Gaming mode, which I assume means it goes quiet while in Gaming mode). Is this something you just have to live with? I recall when I had to re-install Windows, it didn't experience this stuttering, but obviously over several years time more and more 'stuff' got added.
