Xbox One S controller causing major performance problems in many games when connected via bluetooth. Need dev attention. Widespread, many examples within.

Bump.

Can we get a discussion going? The devs need to know about this.

If you're affected, please post your Windows 10 build, and any relevant configuration info, as well as your bluetooth adapter.

I'll do the same here.

Windows 10 - Build 15063 

FX-8320 overclocked to 4ghz

8gb of DDR3 ram

GTX 1060.

This issue was present on both AMD and nVIDIA GPUs, so I'm assuming we can rule out the display driver.

Affected bluetooth adapters (that have shown the issue in my testing) are listed following

ASUS: USB-BT400, USB-BT212.

IoGear: GBU521, GBU321

Mediasonic: BR2531

Soundbot: SB340

If you want to test to see if you're affected, all you need is a copy of Trials Fusion. Connect via USB, put the game settings on anything (any modern system should max this game with 60fps, even some integrated graphics setups), and note how buttery smooth it runs.

Now, connect via bluetooth. Note how inconsistent and stuttery your performance gets.

Go back to the menu. If you've got a particularly low end bluetooth adapter, simply move the controller behind your body, or behind your chair, out of the line of sight of the bluetooth adapter. See how your framerate is directly tied to the bluetooth signal? Put the controller right next to the adapter, no issue. Pull it away, issues. Ugrading to a higher power bluetooth adapter does not fix this problem, as it's not truly a signal issue. 

I've contacted the Trials Fusion developers about this, and their response was (Edited, first draft was paraphrasing. this is word for word) "Thank you for contacting RedLynx Support. This is a very peculiar issue. I reached out to the developers who said, since our game code does not touch the Xbox One controller driver, this is something Microsoft will need to fix. We apologize for any inconvenience this causes"

I will agree only i have games that i have to plug the controller in to play them. but i do notice plugging my s controller in does yeald more frames.

I have a reekfish usb dongle.

So I've done some testing and this issue doesn't seem to affect all games. The issue likely has something to do with the way the game is programmed to access the Xbox controller's input. Also an interesting thing to note is playing over Bluetooth using a Playstation 4 controller does not reduce performance.

Based on a small sample of 5 games I had installed here are my results for the Xbox One S controller

No Performance Hit

• Witcher 3
• Battlefield 1

Performance Hit

• Black Ops 3
• Rise of the Tomb Raider
• Remember Me

If you're looking for a fix to this issue /u/pixelcowboy on reddit has found a workaround where if you enable Xbox controller configuration support in the Steam controller settings you won't suffer any performance issues. This likely means there are some software related issues on Microsoft's end. Of course this workaround only works for Steam games so it's not a full fix.

YES FIXED (working i mean)
