@emiliocobos, sorry for the delay…
Power Saver: https://share.firefox.dev/3RmTVO7
Performance: https://share.firefox.dev/3XzkinN
It’s now stuttering pretty bad in Power Saver and Performance equally, but only on Lunar Lake, not on Meteor Lake anymore. And Lunar Lake has a major caveat that you need to remember to use nightly or else GPU support is missing in Snap builds. So I’m aware of that and it’s not a factor in these profiles.
What I can see is the Compositor and Renderer tracks being practically idle even though I was experiencing stutter. That’s a hallmark of double buffering, but I’ll leave it to the experts to review.
