I've since uninstalled Mafia 3, so I can't check my SpecialK config, I'm afraid. If I remember correctly, the suggestion from the very first reply (simply disabling XInput in the ini) helped.

You can disable XInput support under the gamepad settings. The option is referred to as "Favor DirectInput over XInput" in older versions and was recently renamed "Use DirectInput instead of XInput" in test versions.

Additionally, since haptic feedback is vibration -- you can get rid of this warning by disabling Special K's haptic UI / rumble. Without disabling XInput completely.


If you ever do use a gamepad, whatever is causing this problem on your system is going to cause deadlocks whenever the game vibrates your controller :-\

I had found the haptic option before posting here, but even after disabling it, the error still appeared. So I think this is some sort of mis-detection. I also play a lot of games with my gamepad (just not Mafia 3 ;p), some of them with vibration, and none of them have caused any deadlocks yet. So this is.. weird. If you'd like, I can try to figure out what may be causing the warning/error, though. Are there any debug builds with increased logging, or some debug log settings anywhere?

I do have an NVIDIA GPU, but don't have GeForce Experience installed. Since Special K may introduce the problematic behavior, and I really don't need Special K to hook anything input related to begin with, allowing users to disable any input hooking using the GUI would be pretty neat. Or, alternatively (maybe additionally?), introduce a silent mode for warnings like these.

I think you can open the config file and flip this to false:
(EDIT: The SpecialK config file, come to think of it there might be input sections through the OSD too where this can be toggled and then a game restart should be all that's needed to apply it fully.)

[Input.XInput]
Enable=true

There's a few other [Input. ] sections too but that should be the main one for XInput hooking. :)

And whether it's Steam or GOG it should still work regardless even if SpecialK works closely with the Steam client.
(Though this too can be configured but it seems the game is working without any additional config tuning but there's this gamepad prompt.)

I will give this a try, thank you.

It means the Steam overlay or some other software is triggering an infinite loop.

As annoying as that message is, it would be more annoying if I didn't disable XInput and the game just randomly locked up. You should find whatever software is causing it (again, probably the Steam overlay) and disable it before it causes problems.

Wouldn't this mean that I should be getting lockups when not using Special K, though? Which isn't happening. And Steam isn't even running. There's nothing else related to XInput :/

This thing is driving me nuts. I'm using Special K to limit FPS in Mafia 3, and the error keeps popping up. I don't even have a gamepad plugged in, or any software related to gamepads that's running. I'm not even playing it through Steam! Any way I can turn this off?
