G27 Racing Wheel Oscillation

There is a bug that causes violent oscillation with the G27 racing wheel when the car is stationary. I was able to reproduce it consistently with all of the stock cars except for the Gavril Barstow, the Gavril Grand Marshall, and the Gavril H Series. where it only occurred about 50% of the time, and the Moonhawk and Gavril T Series, where I was never able to reproduce it.

Steps to reproduce in game (according to my testing):

1. Set Force Coefficient to a value of at least 250
2. Set Force Limit to 5 (not completely necessary)
3. Spawn in a vehicle
4. Nudge wheel gently (or violently) to one side
5. Repeat Step 4 if the wheel is not oscillating violently

My wheel settings (in windows) are:

• Combined off
• Degrees of Rotation - 186
• Enable Force Feedback true
• Overall Effects Strength - 100%
• Spring Effect Strength - 100%
• Damper Effect Strength - 100%
• Enable Centering Spring in Force Feedback Games true
• Centering Spring Strength - 50%
• Allow Game To Adjust Settings true

System Info:

OS: Windows 7 Home Premium SP1 64 Bit
Processor: Intel Core i7 4820K Overclocked to 4.4 GHz
GPU: NVidia GeForce GTX 970
RAM: 16GB DDR3

 

I have a Driving Force GT, yet I set my settings to some settings I found on the forum for the G27;

Try these, and post your results back.

 

Yeah. Exactly what he said. Set your settings to those I pictured in the control panel menu, and adjust the settings as @Goosah said in game.
Its normal for Logitech wheels to move back and forth. This is due to the force feedback system.

 

this happens to me as well and my g25 is set to full 900 degrees, strength in profiler 101%, ingame ffb set to default values.
it does not happen to all cars, but for example the 200bx and the sbr will do it all the time.

when standing still the wheel will start violently moving left and right after you "startle" it by moving it a bit left/right and then releasing it.

i played around with different ffb values but i seem to have to lower the values to a level where the ffb is basically useless to get rid of it.
very weird.

 

Can anyone provide video proof? My DFGT doesnt do anything like this despite having a similar FFB system to the G25.
Im hopefully getting a G25 in the comming week or so, so I will be able to test this.

 

I think that it is a stretch to write it that way. Goosah was saying that at 180 degrees and full power the gain will be higher, indicating that overshoot will be worse. Oscillation is not inherent to FFB.

FWIW, arcade wheels are normally 270 degree. That's a pretty small amount of rotation! 180 degree seems incredibly tiny to me and simply isn't what the hardware was designed for.

 

I would need video to see if its the normal logitech crappy FFB system movement or if its really a bug.
And yes, I would never use my wheel with a setting of either 270 or 180. I would want either 900 or 1080. 180 might be the issue. I told him to set his settings to those I posted in the screenshot of my wheel settings in the control panel.
But now that I think about it, I may need to see a video of this issue before I can say its a bug.
Back in RoR there was only one truck that gave me any FFB issues.

 

Just to point this out, I wasn't actually going to play with a sensitivity of 180, but I accidentally forgot to turn it down after doing some open wheel racing in GRID, and I happened to find this bug. I know it is a bug because I tested it out in GRID Autosport and The Crew, and got nothing even remotely close to in BeamNG. The point of this was to let the devs know that there is an issue with the FFB overcompensating in a very isolated, yet plausible scenario. I understand that most people will never encounter this bug at any point, but it is still a bug. Anyways, it stops happening once I turn the wheels range to over 400 degrees (for most cars), and it also never happens when the car is in motion.

 

Fair enough. It does sound like the situation is related to FFB in BeamNG.drive being tied to the physics system. If this behavior only occurs when the vehicle is not in motion it's probably something that can be filtered out without affecting gameplay. Earlier dev posts have indicated that tying FFB into the physics system without hurting hardware or IRL players would be a challenge.

 

It is a FFB issue.
I replicated it with my wheel. Its due to the FFB system of the G27, G25, and DFGT. Its done with gears.
