vvvv beta question
1

I’ve been working on a project which has been ported to the production machine for a week now, with no problems.

This is a 3 blended screen set-up, + 2 independent screens, divided onto 2 machines.

Since yesterday, I’ve started having the occasional renderer freeze. I’ve checked the driver versions and updated to the most recent nVidia ones. Now I have definitely a pattern of system crash, where a Blue Screen of Death comes up after about 3 mins stating:

BAD_POOL_HEADER

Presuming it’s a driver issue, what are the recommended settings for the nVidia drivers?

Rolled back to older driver. Now I “only” get the renderer freeze, after a few minutes. Before that, some artifacts appear on the edge of the 3rd output Frame count appears to be high, but it refreshes at around 1 frame every 2 seconds. Renderer TTY does not present any messages. vvvv version is 31.2.

I think this might be a vsync issue. After changing the nvidia vsync setting to adaptive it improves a bit, but depends on how fast changing the content is…

Have you checked memory consumption?

within vvvv or at system level?

5

System performance monitor doesn’t show any peaks. And yet it freezes. Other than system tools, how can I log errors in vvvv? TTY window is clear as well.

Patches work fine on a single display, so this is most likely a multi-gpu sync issue. If anyone has any experience with nVidia settings for this kind of set-up, it would be very helpful. Thanks.
