I just received my Augury BiSS-C Encoder upgrade kit I ordered, and i have installed it just now.
(upgraded from a 10.000 ppr encoder)
Here are my impressions while using iRacing with 60Hz FFB:
Oscillations are the same you cant use less damping, friction or inertia. ( so i still use 1 1 3 or 1 1 4 depending on the car / track )
The raw force feedback signal feels more clear and less notchy but its still very notchy of course. (rcon 0)
Reconstruction filter 1 and 5 feel a bit smoother on the higher res encoder but there still is a notchy / geary feel. But the gears feel a bit rounder so to speak.
The forcefeedback is overall a bit smoother. But the biggest improvement is when you use very high ffb strength like 12.86A on small mige and 20-50 NM in iRacing. Than its a whole lot smoother than before and also the motor itself feels smoother like it has to work way less hard.
You don’t feel the noise anymore like the motor is struggling / working hard with very high ffb strengths, with the 10.000 ppr it felt like the motor was struggling but that is gone now.
Also with higher damping it feels smoother with less noise also like the motor has it easier.
So because its all smoother now with my new high res encoder its even more easy to run high ffb strengths.
And the advantage of higher ffb strengths is that you can better feel what the tires and car is doing.
So its a step up especially if you like high ffb strengths and use a lot of damping.
Than you gain the most out of the upgrade. So if you use low ffb strengths its less obvious.
But the FFB really is smoother even so that it seems that it feels weaker because its less jerky and abrupt, so you automatically want to adjust for that by setting your ffb strength a bit higher.
Its a bit like coming from driving with no damping friction inertia at all, and than finally start using it you also feel the need to use a bit more ffb strength because it all became a lot smoother.
Just did a few laps with irffb 360hz ffb in iracing and rf2 400hz ffb rate, with my new high res encoder kit and there definitely a step up there too with higher ffb rate signals! Also tried ACC and that’s also smoother. Of course its going to be the same for all the games
Overall its a subtle but good improvement especially if you run strong FFB, it was worth the upgrade for me.
