Force feedback issue

Recommended Posts

Dear developers,

I find that many effects that could have been implemented with force feedback are missing.

 

Examples:

1) When diving at very high speeds the stick in the virtual cockpit shakes violently. My ffb stick doesn't shake at all.

2) When entering a layer of turbulent air there is no feedback from the control forces. When I do that in real life I get a noticeable bump from the stick, followed by shaking/vibration depending on my airspeed and the intensity and frequency of the turbulence. Quite often I get shaken up by a series of sudden positive and negative g forces, e.g. when passing through a thermal draft at high speed.

 

Hardware: Microsoft Sidewinder FFB2

Interresting......may I ask which FFB flight stick do you have? I even did not know that Force Feedback is implemented in anyway in IL-2! I just don´t understand why FFB in PC FlightSim Software and Hardware is not Standard, like it is in PC Sim Racing which I also do besides IL-2. For IL-2 I use the Thrustmaster Hotas, sadly without FFB and for Sim Racing I have a very very expensive OSW Direct Drive Simucube Wheel System with real Racing wheels and Heusinkveld Ultimate pedals. The Force Feedback in SimRacing Software and Hardware is very detailed and High sofisticated.

I wish I would have FFB for IL-2 aswell.

Only way I get force feedback is having it unchecked in-game otherwise it doesn't work. Also- I only get spring effects. MSFFB2 must not be supported anymore...

I use a G940 HOTAS and It's nice.

I don't think it's an issue with my MS FFB2 stick. It has both centering forces which vary with airspeed as well as spring effects.

 

Are there any spring effects when diving at very high speed and the control surfaces and the stick in the virtual cockpit shake violently? That's one example where I believe force feedback effects are missing.

I use an MS FFB2 as well.

 

I think there is a bug with the force feedback control surface flutter effect. I did some testing of the force feedback system causing head movement stuttering. I think the missing force feedback effect you have noticed is being misrouted to the pilot's head instead of the joystick. 

 

Here are the results of my testing:

 

I did some testing in flight:

While parked on the runway with engine off and no wind or turbulence there was no stuttering during head movements.

While parked on the runway with engine off with full wind and turbulence there was significant stuttering during head movements.

While taxiing below 50 KPH without wind or turbulence there is no stuttering during head movements.

While taking off stutter increases with speed from very slight to severe as speed goes from 50 KPH to 150 KPH.

Slow speed flight at 135 to 150 KPH has slightly less stutter.

Enabling Auto-Level(Auto-Pilot) while in flight eliminates the stutter.

Going very fast (over 700 IAS in a Yak-1b) removes the stuttering but when you slow down the stuttering returns.

Losing your control surfaces removes the stuttering at all airspeeds.

 

Testing in game settings:

Disabling Force Feedback stops the stuttering.

Shaking and Feedback Power have no effect on stuttering.

Pitch and Roll deadzones have no effect on stuttering, nor does sensitivity.

Unbinding pitch and roll has no effect on stuttering.

Smoothing reduces stuttering while increasing latency of head motion latency.

Increasing Joystick Noise Filtering decreases stuttering while increasing head motion latency.

 

Removed all USB devices except keyboard, mouse, and joystick, restarted system

Stuttering was still present.

 

Looked into gameevents.cfg and found that these are the events that are being effected by the bug:

event="BC_HEAD_YAW"

event="BC_HEAD_PITCH"
event="BC_HEAD_ROLL"
event="BC_HEAD_TRANS_X"
event="BC_HEAD_TRANS_Y"
event="BC_HEAD_TRANS_Z"
event="BC_HEAD_ZOOM"

 

Tried editing the files in the input folder:

No effect on stuttering. None of the ffp or config files seem to be read at runtime.

Nice report ! I have this shaking occasionally but eliminated it by restarting the game   then carried on without a problum until next time ! can be weeks or month apart!  However there are some issues with force feedback with feedback at various speeds coming and going !   I've always just taken it for what it is but after reading the above report I will take more notice , Thanks  Kalthios  S!    MS FFB Original red button

If your referring to shaking fix by restarting game ! My stick physically shakes for whatever reason from time to time regardless of the aircraft   ! it sort of feels like the stick feedback you get from leaving the top cowls open in the A-20 but happens with any aircraft . hence restarting game fixes it for a time . possibly files not loading correctly .
