Animations slowing down over time

Hi ChristianSiglin,

I'm sorry to hear about the trouble with the animations in your Storyline project. As you have pointed out, your project is extensive and media-heavy, but this should not affect how the animations behave unless corrupt media elements are involved. 

We haven't received a similar report lately, so we can start troubleshooting by ruling out a possible installation issue on your end. If you're already working on your local drive, try running these steps to fix possible installation issues.

If the problem persists, we'd be glad to investigate further. Would you be willing to share a copy of your project file so we can examine what you have set up and rule out file corruption? You may share it here or privately in a support case, where our Support Engineers will work with you one-on-one. We'll delete the file when we're done testing.
