Seems Safari is getting worse, I have noticed my own website: triofleaf.com or ifemoralmajesti.com has more performance issues since updating to Ventura. I have autoplay videos on my home page and other pages. They no longer seem to work with Safari. When I clear cookies however and reload the page it does work, but then navigating through the site and going back to home page shows errors / videos unable to play. I think this update has a few new bugs. I dunno if it's running out of memory or what... but Safari has often been troublesome in comparison with other browsers. For example i'm looking forward to using HTML 5 video AV1 codec to save bandwidth and speed things up for users and move on from very outdated old h.264 codec but so far Safari is holding back the show.
