Character Controller Tick destroying FPS in PIE

Hi guys,

So I’m having a problem I can’t seem to get my head around; When I play in editor my FPS drops steadily over a minute or so from 120, to around 10-15. This suggested to me that something is piling up somewhere in my blueprints. So I used ‘Stat Game’ to try and find the culprit, and sure enough it showed that the Controller is whats hogging precious ms. I have attached a screenshot, and as you can see the Controller is taking 19 ms on tick.

What’s weird is that tick is not connected to anything in my Controller. If I disable tick on the Controller then my FPS is fine and everything looks good, except disabling tick on a controller disables it entirely. If I play in Standalone Game, everything is fine, as in the screenshot below. So this problem only occurs in PIE.

I was just wondering if anybody could shed some light on this, as I have no idea whats happening here really.

Cheers guys!
