Hi jamess, Thanks for reaching out. Performance is dependent on multiple factors which include your system specifications, project's complexity, other applications running in the background, etc. I understand it is difficult to get comfortable with the change in interface, however, there are a few things which can be adjusted. I have a few questions which will help us to understand and troubleshoot the issue better: Which CC version of After Effects are you using? As @Mylenium mentioned, we need details about the computer(OS, RAM, GPU, CPU, etc). Are you testing the performance on a project created in the CS6 version? Additionally, please check out this article: Improve performance in After Effects I hope it helps. Thanks, Shivangi
