Does this mean SMS failed to include those 'two forces'?
With what car(s) have you tried it, to compare from previous/stock FFB?
The two forces are the wheel's momentum in the x and y coordinates (parallel and perpendicular to the direction of travel on the horizontal plane). Apparently SMS felt they didn't add much to the ffb and as such were irrelevant.
Cars I tried:
Formula Renault @ Daytona road circuit:
Always loved this car, now it feels slightly better though a bit lighter at low speeds. Sense of weight increases slightly once downforce starts working. Will need to try again to increase tone further.
Ford GT GTE @ Spa:
Car was ok but used to spin a lot out of a sudden, now I can catch it by instinct really feel that tyre load changing much more than before. Massive improvement.
Radical @ Donnington:
Worse car of the bunch. I mean, it improved a bit, but even with ffb maxed out steering felt floaty. Could be down to car weight. Still, always felt like this car disappointed.
KTM GT4 @ Watkins Glen:
Felt really good. Don't really like the car (feels sluggish to me) but it felt more precise and again, I felt more of what was going on with the car.
I have a TS-PC racer settings are:
Gain 100
Volume 100
Tone 50-100 (depending on car)
Fx 25
I was surprised I Don't get any clipping and it feels good as is. I adjust tone according to car if I want to feel the steering lighter or heavier.
Most consistent ffb between cars for the same settings too. Whereas before I had to adjust volume and tone almost individually, now I just adjust tone and not individually. Big difference.
