Why does my computer make grinding noises when using UE4?
Some really weird stuff is going on inside my PC when using UE4. I have never had this issue with any other application before.
When using certain parts of UE4, my computer (or I guess, harddrive) is making "grinding" noises. The noise differs from what parts of the application I use, which is absurdly strange.
At first, this just sounds like my harddrive dying. But I'm starting to question it, since it doesn't make this noise in any other application, even when using the same harddrive.
That's some weird ass sh*t. Does anyone have a clue what's going on?
Are you using usb powered speakers?

I hope this can be of help to someone else as this was very annoying for me, but turning off Realtime Rendering (CTRL+R) in the viewport has removed the coil whine (definitely coming from the PSU and only with UE4 in the Editor).
