Same issue here.
I can't believe this hasn't been fixed since mid 2017 (and maybe even before that).
I am getting severe FPS Drops (Down to 4 FPS constantly) in many Games that are played with a controller.
Most issues with:
Anthem
Enter the Gungeon
No/no severe issues so far with:
Resident Evil 2: Remake
Assassins Creed [Insert Random iteration here]
The Awesome Adventures of Captain Spirit
Life is Strange 2
Specs:
Medion Erazer X7857
Windows 10 Home Version 1809 (Build 17763.348)
i7 7700HQ
GTX 1070
16GB DDR4 2400MHz
Intel(R) Wireless Bluetooth(R) Driver Version 20.110.0.3 (4th Dec. 2018)
Holding the Homebutton for a couple of seconds to iniate another pairing resolves the issue temporarily.
The only solution for me so far is to connect the Controller via USB cable, as many of you mentioned already.
Since this has so many replies and recommendations: Y U NO FIX DIS M$?
If I wanted to play with a USB-Controller I would've bought one for 5€ on eBay...
