The VideoLAN Forums

I am trying to play a movie, 4K on VLC, and I am getting severe lag to the point where the application will sometimes "Not respond" I cant click any of the stuff on the toolbars, but the movie looks fine as long as i dont touch anything.
i9 9900k
RTX 2080
are my specs
The movie works fine on KMPlayer, but VLC basically crashes, I mean I literally can't touch anything in the app or fast forward, everything except video/sound struggles badly
The movie has HEVC
If you need anymore info let me know

If it doesn't help then open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.

Also upload a short sample of your original problematic file to WeTransfer.com or Disroot.org and then post the link to the file here.
