Editor lagging constantly on play

Hi folks,

For a project I am working on, I am noticing that the editor I am previewing the build with lags constantly for several seconds when playing. However, on another computer, it is working smoothly.

The computer with issues has an Nvidia GTX 980 with 16GB ram. The working computer has a GTX 1080 with 32 GB ram. Obviously, the more powerful computer is expected to run better, but my project is fairly simple and does not require a lot of graphical processing power. I am trying to diagnose what might cause this issue, but I have no clue where to start, and there are many forums with many possible answers. Could anyone give me some basic pointers of things to look for or settings that might be causing this issue? Thank you!

Maybe it’s in the process of baking lighting or something? That would be a computer-specific thing.
