As the title says, when I load up a game with my controller turned off, games run at full speed.
As soon as I turn on the controller emulation slows down to at least half speed, along with horrible sound stuttering.
System:
Windows 10
I7 6700k
Geforce 1080
16gb DDR ram
NVME m.2 drive
Xbox One controller via bluetooth
All other cores work perfectly. What could cause an issue like this?
