The last driver released that does not cause stutter was 17.7.1 which has a maximum recording bitrate of 50Mbps.
Every driver since then has had a maximum recording bitrate of 100Mbps which causes stuttering recorded videos no matter what you set the Bitrate to. Even less then 10Mbps recordings have the same issue.
This problem affects multiple AMD users as multiple reports have been made here, perhaps all AMD users affected.
