Quantized notes sound un-quantized

[grs]

Just keeping an eye on this thread.
Did a test with an old 1.8Ghz laptop, fresh install windows xp.
Cubase 3.1, and virus TI install.
I got almost sample accurate timing with a test project that I normally get plus or minus 8 milliseconds with on my AMD Athlon 64 x2 Dual 6000+

The only stand out differences are:
Intel not AMD
Laptop only has USB 1.1
Laptop is self contained, AMD system has lots of cables going in out of it (RF probs??)
Laptop has almost nothing installed, AMD has a hundreds vst/vsti, Net, office, graphics apps all over it.

I'm going to devise tests to eliminate some of the above like a fresh install on the AMD with on HD, no peripherals etc.
