Tells YouTube that your browser only supports videos at 30FPS or less, which switches all 60FPS videos to 30FPS and allows old computers to watch high-resolution videos without stutter!
< Σχολιασμός για τον κώδικα Disable YouTube 60 FPS (Force 30 FPS)
Worked great until yesterday, but now for some reason it disables HD videos (only 720p and below is shown).
Maybe, youtube doesn't support 30fps for 1080p+ anymore?
HD still works for videos which have only 30fps source, but as soon as a video has 60fps option, HD resolution disappears.
