What you have there instead is a typical example of a bad driver for Windows 7 vs a good driver for Windows XP. Blame the manufacturer once you find the source.

Actually, Mario, I'm not getting any spikes... never over 300, which is usually while I'm watching the news and doing backups at the same time... very IO intensive stuff.

THIS machine doesn't have the audio and video problem. That's a whole different computer that also has no DPC spiking, just a consistently high delay... I never did figure that one out, I needed it working for a demo so it went back on XP real quick...

Still there is an audible difference in sound between XP and 7... as I now have my main machine dual booting, I can hear it... The XP sound is clear, almost transparent on FLAC sources where the Win7 machine is "cloudy" (for lack of a better term). It's the same hardware so I have to write that off to drivers as both are running Media Player Classic.

(If you're concluding that I'm all about AV, you're correct. I made my living at it for a long time)

Oddly, now that I'm dual booting, this install of Win7 seems better behaved... my DAC is working on both (which it never did before) but I haven't had the chance to check the other stuff just yet... Still drops keyboard characters though...

I dunno... An AMD 64x2 at 3ghz should do better than this... There's a noticeable difference in performance between 7 and XP... XP is clearly faster.

It just fries my gonads that I spent $1200 on several copies of an OS I'm likely to relgate to the dustbin...
Win7 Pro is $329.00 in my area...
