I believe it's mostly iRacing that is super bad with impact signal spikes. AC for instance doesn't do that.
We had some discussion on that on GD forum, read starting from this
post
But yeah, if nothing helps, just drop driver strength, it's easier to let crazy spikes to just clip than visiting doctor's office after hitting the wall.
iRacing is where I'm spending most of my time. The irony is that it "appears" to be track dependent even using the same car. I was just learning Mount Panorama and was completely shocked by the amount of impact I got. I was turning away and my hands were crossed when it hit me. Now I'm on Autodromo Jose Carlos Place, and feeling gun shy.
FWIW, the curbs come through tactile only in iRacing not steering. I was very surprised by this, however the tactile and audio line up perfectly and I feel and hear the curbs nicely because of them. I know this is very different between games based on the initial complaints about curbs in ACC. I do run one transducer with some surface texture and rpm that comes through the steering wheel which is sort of like running effects with an AccuForce wheelbase.
Most of the videos going on about how great the SC2 is are showing iRacing where I spend most of my time. I also spend some in Dirt Rally 2.0. I haven't touched (AC, ACC, PC2, or DR 1.0) since getting the SC2.
I've got Dirt Rally 2.0 acceptable, but there is no improvement over the CS 2.5 that I can feel. iRacing is better but it's subtle and I do think if you aren't running at a higher strength than the CS 2.5 is capable of delivering that you are missing out on what it does do.
I understand that you don't "need" tactile or motion to drive, but I find it a lot less involving and dead without them. I know that some people feel that way about driving without a dd and that's fine. As was said before different strokes and I'm not suggesting my opinion is better than anyone else's. Not only that I am absolutely not an expert at any of this and I still don't consider myself a good driver.
Case and Point of why my opinion barely matters:
When I was living in Dirt Rally 1.0 brake modulation had a much lower importance than it does on the track. As a result I loved my seat out of a VW Passat. Now that I'm using stiffer brakes with the Nm up pretty high so I can modulate better I'm finding my seat doesn't offer enough back support so I'm moving to a racing shell seat.
In threads where people were asking for seat suggestions, I would frequently explain that I got a great seat out of a wreck for $40 that I loved and that there was much more engineering in a production seat like that than a racing seat.
But my needs changed when I changed what I was using my rig for. For rally that seat was great! For track use with soft brakes it wasn't a problem either. When I got Sprints and cranked up my brakes so I could modulate 60-80% brake better, my performance improved and I could hit a corner better, but it required significantly more force and my back suffered for it.
I've changed my mind on a lot as I've gotten deeper into sim racing and I'm not trying to disagree with the opinions of other people here who have orders of magnitude more seat time racing than I have.
