Hi there, did you guys find any further resolutions on this issue?
Am having a similar issue here - high end i7 server, with quadro m6000, raid 0 array, and watchout 6.2.2 on windows 8, running four custom rez outputs at 30hz. Seeing stuttering on four HapQ videos (about 1.5x 4k worth of pixels total). Have pushed these servers much harder without issue before.
Seems to be some correlation between going offline and back online (sometimes induces stuttering), and remoting into server to "relaunch" watchpoint (seems to fix stuttering temporarily).
Any discoveries or thoughts? Thanks!
