Choppy 4k playback on VLC 3.0.2 on Vega
Posted: 12 May 2018 22:02
Hey everyone,
This is a continuation from this thread: https://forum.videolan.org/viewtopic.ph ... 80#p470180
I am now on VLC 3.0.2, have updated my GPU drivers to the latest version (18.4.1), have tried setting my video output and input/codecs setting to D3D11, have tried disabling hardware acceleration, all while setting VLC to realtime priority through Task Manager, all to no avail. I've also tried pausing the playback for a few minutes in case it was a buffering issue, but the choppy playback continues regardless. The videos I'm trying to play are all x265 HVEC 10-bit at 2160p. My computer has no problems playing these using other video players like PotPlayer, so the issue is definitely with VLC. Any help would be appreciated.
Here are my specs:
CPU: 2xXeon E5-2667v4
RAM: 256GBs DDR4-2400
GPU: RX Vega 64 LC
Hard drive where video files are located: Samsung 850 PRO 2TB
OS: Windows 7 Ultimate x64
Here are the logs when trying to play one of these video files (this is with video output and input/codecs set to D3D11, verbosity set to 1, and vlc.exe set to realtime priority):
