High CPU usage on safari? MacOS Sonoma

Hi, just set up my i5-12400f and rx 6700 xt system and everything runs fine except I get very high cpu usage while watching videos and browsing the web. Im not sure if it’s cpu related or if the GPU isn’t being used. Everything else is buttery smooth at 165hz.

Ive tried imacpro1,1 and macpro7,1 smbios but it doesn’t fix the issue except that the imacpro1,1 gives me better geekbench scores.

Could it be some issues with Sonoma?

Ive done a lot of searching beforehand and im thankful for any kind of help i can get
