Force feedback update rate adjustment

I wish that somekind of Force feedback update rate adjustment would be added to rf2.
According to my experience limiting ffb update rate from default value in rf2 is beneficial with OSW direct drive servo wheels.

With earlier rf2 builds there was "skip updates" setting for ffb. By that it was possible to limit update rate. Now that setting is gone.
With full ffb update rate it feels to me like that with direct drive servo wheels, high frequency vibrations are highly exaggerated compared to real life and more mainstream belt driven sim wheels. This causes the ffb to feel very harsh.

To compensate the harsh feeling lots of filter or smoothing needs to be used. End result is that ffb feels much more numb compared to settings with limited ffb update rate and minimal or 0 amount of filter/smoothing. This causes me to stick with the older build now, but I hope that the skip updates setting could be given back in next builds.

 

Here a quote from Niels Heusinkveld from reiza forums: "Pure 360hz is the recommended for purest & higher fidelity FFB; Pure 180hz may be better suited for high end wheels with performance issues triggered by the high rates"

So Automobilista has update rate adjustment and there is a real reason for it.
For the same reason rfactor 2 should still have it.

Afaik nobody has gotten the simucube yet.....at least i'm still waiting. But i for sure am curious about the feeling of dd wheel with simucube

 

STM Disco.

This thing might be about my personal taste on ffb. I haven't seen much other osw owners complaining about his.
But still atleast for me it would be nice to have that adjustment.

I have to say that many cars still feels good with full update rate and filter at 10. But with some cars there is more of those high frequency vibrations.

I just did some driving with them (cars with vibration problems) again and started to think that maybe the problem is in my head.
Probably the wheel outputs the ffb just like it should and it would feel good to every one else, and i have somehow managed to produce a problem in my head towards high frequency vibrations on ffb.

 

It would be very interesting to hear about differences between servo drives if someone has tried more than one of them.

 

Now after spending more time testing I have to say that having some kind of low pass filter for ffb definitely is beneficial, for me atleast.

Other sims has adjustment for this and it allows me to get better feeling ffb out of those. Same thing with older build of rf2.
Some cars in rf2 feels ok even without limiting ffb update rate, but for some cars i can't get good settings.

I really hope that the ffb update rate setting would come back to rf2 in future builds, atleast if it was easy thing to do.

 

I run an OSW with ST Disco board.
In the previous build I was forced to lower the update rate purely due to Cpu spikes.
In the latest build it seems to run fine in that regard.
Personally I havent had a desire to lower the high frequency feedback. Again it might be in my head but
I feel the front tyres losing grip more clearly through the higher frequency feedback.

 

I still think there should be adjustment for the ffb update rate. Even AC has one in UI by which you can half the ffb update rate.

Lowering the update rate under certain frequency seems to give more pleasant feeling force feedback. Especially when using ffb on high forces. The difference is very small but it still sucks lot of the joy from experiencing the ffb.
This is like having a really good and expensive subwoofer, but the not being able to adjust the low pass filter low enough.
You will get too high frequencys out of the subwoofer which it can't reproduce with good quality.

I think the same happens with big servo motor. there will be reconances in the motor and rig that will worsen the ffb quality.
In the search of maximum ffb quality, the update rate setting would be very helpful.

Ps. I don't think it's my rig resonating because i tried isolating the motor from my rig with rubber mounts.
