Netflix open causes massive frame stuttering
I listed this as UE 4.21, but I'm seeing it also on UE 4.18. Like the title says, having Netflix open causes stuttering of my game. Every second or so, I see a freeze that lasts about a fifth of a second, rendering my game unplayable. Details are as follows:
edit - the stuttering occurs even if Netflix is paused, and minimized in the background. Other streaming services like YouTube does not cause this issue.
I ran profiler (image attached), and it shows FFileTransferRunnable and FMessageBug.Router taking large amounts of CPU Stall time. Googling around didn't give me any hints.
Has anyone else seen this issue? Its been plaguing me for months. I don't want to have to put up a message to users "turn off Netflix to play this game, even if your computer is amazing".
I observe the same problem. It happens with Netflix as well as with HBO go, perhaps it's related to some kind of DRM. I get FPS drops twice a second or so, it's unrelated to the engine you use. Which browser are you using? This happens when I use Chrome, switching to Firefox solved the issue for me.
