I have an i7 3770 with quicksync on. The few errors i see in the logs include:

Are the error I speak of.

Do you have the full DEBUG logs (not just ERROR excerpt) which capture the failure that I can inspect?

I responded based on what you provided; nothing more.

Given there were some errors with certain CPUs in 1.29.1, until proven otherwise, it’s possible 1.29.1 hard-fails with a 3770 during HW detection.
