I’m extremely confused at the moment and I’m not sure if this is something caused by the way unreal engine games are coded, however I discovered after attempting to run my compiled game twice on my computer-the framerate immediately halved from 40-50 to 20-25. Additionally if I open up a 3rd window of it it’s reduced down to 14-15.
And if/while I hold a window,where its process becomes frozen, I can see the first of 2 windows return back to 40-50fps immediately. It’s important to note in the editor it runs at a clean 60fps. Why is this happening with the compiled project?
This is with a basically empty scene without lighting on Windows 7 64bit with unreal engine v4.5
I’d really appreciate if someone has an idea of how this is happening.
