SBP Struggling during playback

I have a new laptop, expensive, good GPU and all that. I was running SBP on a 7 year old mac before this new laptop and it worked fine, but now whenever I try to play a scene, especially if there are multiple short panels or camera movements, the playback will struggle to play smoothly, instead starting and stopping on every new panel. I’m not sure how to even check what the issue is here, and I was hoping someone had some insight. Thanks.
