Capung , I really do not perceive any lag/stuttering in that YouTube video of yours - I suspect it boils down to your machine (more specifically GPU) which is perhaps not powerful enough to handle 60 FPS + Full HD videos, even though it should, so it might be a driver / codec problem. May I ask, you perceive lags both when viewing the video on your machine as a file and when watching it on YouTube?
Can you make sure your AMD GPU drivers are up to date? Can you try to view the video on your machine (as a file) with the VLC player (its free to download)? I suspect you were using windows media player before? That player is well known for having codec problems with our videos often resulting in stuttering and such not perceived when using an alternative player like
Yes actually it only happen with Windows Media Player, i just realize it after upload it on Youtube lol. VLC solve my problem. Thank you very much!
It looked perfect to me.
The default Windows media player for videos is awful and almost any video looks bad in it, Download VLC (https://www.videolan.org/vlc/) and give it a go, it'll harness your graphics card for play back.
Thank you very much. That is true, stuttering only happen in WMP. VLC solve my problem
