10.6.0, 10.6.1, 10.6.2:

• Needs 240ms of video offset to stay in sync for the first few seconds of playback.
• The video drifts in sync; got to about 100ms earlier after 30 seconds of playback.

10.5.0, 10.5.1, 10.5.2, 10.5.3, 10.5.4:

• Needs 240ms of video offset to stay in sync for the first few seconds of playback.
• The video drifts in sync; got to about 100ms earlier after 30 seconds of playback.

10.4.3:

• Needs 90ms of video offset.
• The video stayed in sync for an hour of playback. (checked every 5-10 minutes)

Conclusion: I'll stay with the 10.4.3 driver.

Ps. I'm not filing any reports to Blackmagic or Avid as my system doesn't qualify for Pro Tools 12. That is, I don't expect to receive any help anyway.


I'm curious: What machine and video hardware do you use?

I can state that too the newest drivers have those symptoms the high need of video offset and that weird drift that it does. I go back to 10.4.1 again stable and stayed in sync for ours (i did the same test) never tried the 10.4.3.
