Force Feedback Induced Camera Movement Stutter


Recommended Posts

  • 1 month later...

Hi,

 

I recently brought my old Sidewinder Force Feedback Pro joystick back to life and noticed the same stutter and sometimes complete halt of the game when I activated the force feedback in the options menu.

 

Particularly with the Sidewinder Force Feedback Pro, the ffb effects are transfered as MIDI commands via a serial COM port. While trying to solve other issues with the joystick I found a rather strange work around to the stuttering issue that might work for those with other ffb joysticks. 

 

Just by opening a serial terminal software to monitor the joystick COM port, all the stuttering disapeared!

I'm using Termite, but it might also work with any other serial terminal program like PuTTy or RealTerm.

 

It might not work with the other ffb joysticks, but I think it's worth giving it a try.

In my game when i use flyby camera and mouse look i notice that airplane tail and ground texture is shaking for 1 second after i move the mouse, i don't know how to fix this, after each mouse movement i see this effect.

Hi,

wanted to give Box another try but .... it just won't work like it should.

is there until now any solution available for the trackir + ffb problem. I tried the solutions like smoothness and fiddle with the trackir profile, inertia to 0 etc ..... but all this just don't really help.

For me BOX ist just unplayable with my MSFFB + Trackir. DCS works just fine.

So is there a way to play this game with my setup?

Unfortunately not possible to play without getting camera movement problems with the MSFFB2 in this game. I just moved on to other titles, the devs are not going to fix it.

I have been using my FFB2 + TrackIR 5 since day one I do not see any stuttering.

 

Let's review our settings and see what the issues is.

 

Start by posting your camera settings.

sorry, don't have it installed no more. But as you see on this topic and others, almost all, if not all have stutter problems with trackIR and ffb.

And the "fix" was to set the camera smoothness to 100 and inertia to 0. But even this didnt feel right.

 

Anyway thanks for your offer. I will try the game some updates later in the future.

Ok i gave it another try.

With all what is said here before and caping the frames it is more or less playable.

Now i was reading here somewhere a lonely post where someone reports that, when he fires his guns with his MSFFB2 the stutter is gone. Well i thought ....nonsense. But right now i tested it and yes, for example when i fire the machine guns in the spit, i can look around buttery smooth. So maybe all this is camera related, but give it a go and try yourself.

I have TrackIR and MSFFB2 working together without a problem. They have worked  with no problems for more than a year. Sorry I don’t have any advice to help get yours to work. Perhaps this has nothing to do with the devs and is a settings issue.

I don't know if you read the previous page of this thread or the Dev Diaries, but there is a workaround implemented by the devs some months ago, adding a line to your startup.cfg file:

 

3. Force Feedback joystick owners who experience stutters can alter the new value in startup.cfg that governs the maximum frequency of FFB effects polling to try to eliminate them (update_freq parameter in [KEY = force_feedback] section can be set to a value from 0.5 Hz to 10 Hz, example: update_freq = 10.0);

 

Try with different update_freq values, combined with your camera view smoothness, to see what works better for you.

It does improve a lot the stutters, at the cost of some responsiveness/lag in the shaking FFB effects.

Then you still have a pretty alienistic PC.. Maybe it helps a lot to figure it out ?

Why didn't anybody bounce on that com ??!

 

It looks very promising on a single experience. Several years I didn't fire BoX now and I bought a Odyssey + VR in the meantime (still didn't try it) but I'd like to have a look on your work around suggestion for 2D.

 

On the problem itself, if we try to sum up all that ****ing problem which lasts since years now :

 

# Plenty of people using FFB (Microsoft Sidewinder FFB2 mainly) + TrackIR (5 mainly) are reporting abnormal stuttering since years. BUT :

     # Some people are experiencing the same only with Tir.

     # Some people are experiencing the same only with FFB (?).

     # Some people have no problem at all.

     # Some people are experiencing the same problem in other titles (DCS). Most people report this works like a charm in this very DCS.

 

# Devs denied the problem for a long time (was hardware related, settings related, etc), then provided a few tips to improve the things a bit.

 

# Some people provided some work arounds but there hadn't been a lot of people adding their positive experience by trying it.

 

# Some people unfortunately just left the game... :(

 

Do you guys see anything in that desert ?

I am not sure what video card/Processor/RAM one has installed as anything to do with anything.

Remember The FFB stick I used was developed 12 yrs ago! Unless you are running a PC built in 1997 - I am sure your hardware can handle it.

 

The MS Force Feedback 2 Joystick doesn't have software per say but Win 7 & 10 both recognize it and it can be calibrated, but not programmed, I think this is the 1st issue.

The 2nd issue may be peripheral connections - I connect mine via a USB 3.0 powered hub and a direct connection to the PC via 3.0/2.0 USB will also work.

 

If you are using some 15-pin hack - I don't know what to tell you.

Ther is nothin inside ms ffb2 what can be or need to be programmed. Deadzone setting was software feature of old win 9x/2000 drivers, when PID part of HID spec was not implemented, but in windows XP and later PID driver is present so joystick drivers is not necessary.

Well. I spent some time and made my own FFB compatible usb joystick controller. And guess what - no stutter. I cant say what gives, i just emulated ms ffb2 on stm32 board

https://forum.il2sturmovik.ru/topic/12943-народный-ffb-возможно/page/5/?tab=comments#comment-804722

My controller is 1ms so it can handle 1kHz report rate. But ms ffb2 descriptors say the same. No idea why my is not stutter in games, but with ms ffb2 i have 4fps in warthunder and alot of stutter in il2. 

 

To make you understand how bad situation is. It is not just il2 and MS FFB2, all games, for example - racing ones, with ffb devices are affected. 

Old devices that is. New wheels works fine, just as my stm32 prototype.

FreeJoy will roll out forcefeedback compatible firmware in January, if anyone interested.

Right now im trying to find out what is it, where is the problem. With COM port mouse to look around in quick flight, stutter still present. So it is not a USB issue. Something inside PID and HID libraries i bet(but why TrackIR is affected, its not a HID device and data from it pooled totally different way), but we have no sources, cant peek inside...
