Simulate Framerate Lag

How do I simulate frame rate lag for testing?

You can try intentionally yielding every so often inside RenderStepped.

If you are doing it in Roblox Studio, I do have a plugin to help automate it.

You can simulate replication lag by setting File --> Settings --> Network --> IncomingReplicationLag in studio settings.

I am not sure why testing your game in low fps would help? You should be changing how you game is made to run correctly on devices not simulate how well you game works with low fps.
