Joystick inputs lag or missed in some games

[invertendo]

In two games, NFS most wanted 2012 and The Crew Unlimited, steering wheel input lags or is missed for several seconds at a time when playing through vorpx. So imagine you’re trying to steer, the game will pick up the steering input after a long delay, but it’s not a continuous lag, it just misses all other inputs. Keyboard input seems fine meanwhile.

What’s really interesting is that there’s no delay in the force feedback.

(Actually NFS used to work for a minute or two on an earlier version and then would crash. On the latest version it doesn’t start at all. )

The Crew Unlimited uses a dinput.dll replacement mod so that might be causing an incompatibility. Does vorpx patch any of the direct input joystick functions, and if so, is there a way to disable that?

Almost certainly this:

Many games cannot handle simultaneous mouse and gamepad input.

If you use your gamepad natively, i.e. vorpX’s ‘Gamepad Override’ setting is set to ‘Off’, but you still use mouse emulation head tracking, you get symptoms like the ones you see in games that can’t properly handle mouse and gamepad input at the same time.

To deal with that you have three options:

1. Enable the ‘Gampad Override’ setting, which enables a freely configurable gamepad to mouse/kb mapper.
2. Disable the ‘Gampad Override’ setting and then enable ‘Headtracking as Gamepad’. Caveat: Not really recommended in most cases due to high head tracking latency (lag) caused by games filtering gamepad input.
3. Disable the ‘Gampad Override’ setting and set ‘Head Tracking Sensitivity’ to 0, which resolves the conflict by disabling head tracking.

Did you issue an update? The wheel is working today, as well as head tracked mouse look! Vorpx only prompted me for a game database update, which I did.

The game lets you use the mouse to look around while driving with a wheel and vorpx is able to use that. I restarted the game a couple of times to confirm it wasn’t a fluke.

Yesterday’s profile database update ‘only’ contained updates for some shader definitions that got broken by game updates, nothing related to your issue. If you encounter something like that again, keep the three options mentioned above in mind.
