I don't think so. I'm definitely not an expert in operating systems, but 
couldn't it have something to do with the scheduler in 2.0 or the 
various changes in the new kernel? I remember FreeBSD was extremely 
jerky, too (that's why I switched to NetBSD 1.5 and 1.6), but people say 
it's much better now with the new scheduler in FreeBSD...

And like I said, NetBSD 1.6 was very smooth on the same PC with the same 
software, drivers and settings. And multitasking in Linux is also a lot 
smoother than it is in NetBSD 2.0 on the same PC, with the same
