I forgot to mention that i've done the tests in fullscreen playback.
In windowed mode , the videos that are played with MPC-HC are still stuttering , but way less than in fullscreen .
Can you give an example of the video that stutters? or a codec info of the file? I checked two random files I had on hand, and they played just fine; I didn't observe high cpu utilization that would suggest the video isn't accelerated by gpu, either.
I don't really know what do you mean by "codec info" but i can give you some details of the videos that were played : 1080p60/1080p24 ; MP4 ; Stereo/5.1 ; High bitrate (~20Mbps) . If i try with other players like pot player , or VLC , it works just fine . I tried to reinstall mpc-hc and i did a clean install of the new adrenalin drivers as well , but the issue is still there .
Bug? Give pot player a try? I tried playing using pot player. Ran okay so far. Don't have super-res, freesync, enhanced sync on though.
Another topic (also a bug) - I faced something strange, while playing Wolf.TNC Amd's preformance metrics were showing gpu utiliz. 100% all the time. After I quit the game, gpuz-, hwmonitor reported 100% too. Idle temps were higher than normal too. 54c. Only win 10 stats showed normal usage. Signed out/signed in, bam! Normal temps, usage in every monitor again. Something is wrong here. Anybody face this?

Pot player , VLC , Movies&TV , Windows Media Player - all these players are working just fine , the only one who stutters is MPC-HC . I tried to reinstall mpc-hc and i did a clean install of the adrenalin driver as well , but the issue is still there.
About your issue , i currently can't test the new Wolfenstein game , but i'll make sure to do so when i'll have some time

I found out that Enhanced Sync is making the MPC-HC playback to stutter , but i don't know exactly why , as it works perfectly with other players .
Enhanced Sync ON + MPC HC = stuttering ; Enhanced Sync OFF + MPC HC = no stuttering ; Enhanced Sync ON + other players = no stuttering
AMD , can you please investigate this strange issue ?
