all of a sudden I have performance issues with my FF800 when using onscreen video. So I checked older projects (few weeks old) -> same behaviour. The weird thing: it’s not a CPU issu, playback via Asio4all onboard sound is perfect.
The only thing I can think of: I had installed QT 7.7 but gone back to 7.1.5, 7.4.5… no change.
I’ve started hunting IRQ settings etc. and see the FW chip and the PCIexpress bus seem to share IRQ19 (along with USB), but as I am using a (the same) laptop, things seem fixed and not changeable.
Very weird - I cannot think of anything crucial I have changed, installed, uninstalled…
Win7 64bit, Nuendo 5.5 32bit
Any ideas? I would appreciate all things worth trying, this has me completely stumped as it actually just had been working fine (back then also with an MBox 2 Pro which I had thought would be rather flakey asio-wise).
Thanks for taking time to help!
PS: How do I update my signature in the new forum… :-\
