Hello everyone, playback is lagging, even at blank projects. I have tried all of those tips https://www.premiumbeat.com/blog/premiere-pro-lagging-fixes/ and more but nothing seems to work. The RAM and CPU are fine, and the playback of the same video plays normally on After Effects. I now realized that when I'm changing the resolution/quality of playback and paused to 1/2 or 1/4 it looks like the quality still plays at Full. Thank you!
Update: I noticed something really weird, if my audio hardware is set to speakers or headphones the playback is lagging. If it's set to my headphones but my headphones are turned off, I get an error message "the previous audio device configuration is no longer available." But the playback is not lagging anymore. The issue with this is that can't hear anything.
