For sure, don't run outlook while you're testing . Make sure you are NOT using the (legacy) version of the MS firewire driver.
Shouldn't need to run in compatibility mode .

Great...er...uhm... OK, CLEAN install. 1.18.5. firmware 1.2.5.6, driver 3.5.0.7171, successfully ran the full calibration of tests. And now the "CRS disease" sets in. 1. I am starting with K5FR out-of-the-starting gate. DDUTIL (which I had before) and VSP. But I don't show any actual serial ports on my machine since I installed Win7? I can create a pair of virtual ports using VSP, but that's no help! This is simple, but I forgot something. 2. DPC laency is consistently 150 microseconds (FINALLY), but the audio quickly degrades into a raspy type of audio and the CPU util jumps up to 75%. The audio also sounds jumpy. Buffer is on 2048. I am not running anything but outlook and SDR. SDR is showing like 25% of CPU. Next biggest consumer is System Interrupts a 10%. When I run SDR in XPSP3 compat mode, things seem to be a LOT better, like 7% from SDR. Is that how I am supposed to run? (maybe I did not get a copy of the memo?)
