Question: My old MacBook Pro 15" 2015 with Mojave playbacks very smooth 60fps 1080p video in REAPER (AVFoundation decoder). How to get the same smoothness 60fps playback on 12-core PC (Windows 10)? I tried different ffmpeg/vlc/dshow decoders and used recommended codecs, but I still jerky playback ~35fps in blank project (only video). Doubling the frame rate to 120 fps doesn't help. Video frame rate in the Project settings corresponds to the video item properties.

    What video renderer mode? Are you screens using hidpi scaling?
