The two sys files are quite normal.

And mixer and settings are just two small control applications, not really part of the driver as such. No need fo 64 bit here.

I've got my new win7 64bit installation up and running, dual booted with my old trusted XP music partition. Tonight, I've compared the performance between the two operation systems. And XP do perform a little better here.

Projects that are running at about 80-95% (ASIO meter, with a few peak led blinks) on my XP setup, goes a little higher on the win 7 setup, where the peak blinks are more frequent, nearly constant lit. The sound quality (clicks and such) on high loads are therefore a little worse in the win7 setup, but not much worse then on XP.

It's the 32bit Cubase version I've installed on both setups, and the plugins are all 32bit.

Now I ask myself, why do XP perform better than win7? Hmm.. The PDC latency is a little better on my XP setup (about 30-40 us), and (60-100 us) on win7. I've fiddled with win7 optimization all night, and just can't get PDC down to the XP values. The usbport.sys and a atapi.sys driver are the cause that brings PDC more up then on XP. I don't know, if an older usbport.sys driver would change anything, but for now I'm using the .sys drivers that comes with win7. Maybe the double up PDC latency on win7 is the cause for the worse ASIO driver performance. Could also the core win7 OS, that just is slower than XP, don't know?

Do any of you have performance compared both XP and win7, and what are your findings? Have you managed to get your PDC down to a minimum (0-20) on win7? If so, how did you do it?

So nice of you Chris with this info. I always thought, that PDC was the cause of software drivers that behaved badly. But maybe it's the older hardware I'm using... Asus P5K Deluxe (P35 chipset), Q6600, ATI X1550 gfxcard... together with a pretty new win7 64bit + SP1. I think the P35 chipset came 2006/2007. So the comp is about 5 years old. In fact I once tried to plug a 2010 ATI GTX640 gfxcard in the x 16 slot. This gave me the bad red peaks you're talking about, and with the standard ATI driver. There was nothing to do, that return the gfxcard. Before that I had an older Geforce G8800 GTS card (faulty now), which was running fine in the mobo, no peaks. So when I returned the GTX460, I got hold of a passive cooled ATI X1550 , which gave me very low PDC latencies in XP. And as said, about double up on win7.

But I hear you. I shouldn't be too concerned about the 50-100us PDC. It's not as steady as I would have want it to be, but maybe it doesn't matter much as long as PDC in down at max 100. I may need to buy myself a new Sandy Bridge system, or wait for X79. I don't like the ITE PCI -> PCIe bridge that is mounted on all Sandy Bridge mobos. I'm not 100% sure if this would create PDC problems for my HDSP 9652 I/O PCI card, but I could imagine that it would going through a chipset + maybe ITE driver? After what I can read, Intel has fixed some firmware stuff in the ITE chipsets, so that PCI audio performance should suffer from the bridging. And I don't think the X79 chipset will support older PCI cards directly, unfortunately.

But thanks for the link. Now there is some more stuff I can study on, hopefully making my system even better for audio than it is. As I still don't like, that ASIO on XP performs better than on win7.
