1. I have found that using the SVGA graphics driver over any proprietary driver (ATI, NVIDIA) has a *huge* impact on overall latencies and available I/O bandwidth.
It looks to me that graphics cards have a higher priority than anything else on the I/O bus; so what I have experienced is that when I had issues with glitches in sound quality, these always disappeared after reverting to a standard SVGA driver that shuts down all the I/O intensive GPU work that otherwise occurs.
Of course since this disables video acceleration you will not be able to enjoy high res movies etc. on that machine anymore. So this tweak is quite extreme but the must impactful change that I have found with regards to audio quality.
{how to change: right-click on Computer, -> Device Manager, -> Display adapters, double click the one you are using (e.g. NVIDIA), -> Driver tab, -> Update Driver, -> Browse my computer for driver software, -> Let me pick form a list of device drivers on my computer, Standard VGA Graphics Adapter}
2. Update to Vista/Windows 7. One thing that some people don't realize is that these newer versions of Windows support the notion of I/O priorities. This helps a lot to keep any background activities from interfering with playback. Win 7 in particular also has an improved process scheduler that is more effective than both Vista and XP, in the quest to eliminate jitter you have to take any advantage that you can get ...
to be continued ...

Nice Moritz, thank you.
I have the hunch that you may know some more things that can be of good help. I hope it's allowed to send you an email about hat.

No problems over here on W7:
Even using "Aero Themes" with nVidea 9800 GTX.
Is this the difference between drivers or OS ???
I would surely use the standard VGA driver and a vanilla video-card in my
Audio pc, because you don't need it.
But Gerard I bet you get better results on W7.....

I am also on W7 and I can confirm that there is no problem (similar picture). I do have nVidia driver active, however it looks like W7 can handle it easy. I did switch to Standard VGA but this does not yield any significant improvement in Latency. So I switched back to my full HD resolution mode and I like it a lot!
Cheers, Eric.

OCZ Vertex 60GB (223,-) or Intel X-25M 80GB (219,-) http://www.ocztechnology.com/products/flash_drives/ocz_vertex_series_sata_ii_2_5-ssdhttp://www.intel.com/design/flash/nand/mainstream/index.htmThe Intel is even cheaper now, IMO I would go for the Intel. There is no difference in Q, I guess, so take the cheapest (Dutch) and biggest. Roy Do get W7, you may even like it........... |

it could be that the answer is to use a multicore CPU (e.g. quad core) as an alternate workaround for the graphics driver issue (e.g. fixed affinity on CPU 0). I am also on W7 and I can confirm that there is no problem (similar picture). I do have nVidia driver active, however it looks like W7 can handle it easy. I did switch to Standard VGA but this does not yield any significant improvement in Latency. So I switched back to my full HD resolution mode and I like it a lot!
