Game Input MultipleXer

Using Simucube with GIMX and Drivehub on PS5 for GT7.

All works, but whatever rumble/vibration etc there is for road feel goes away anything over maybe 30-40°. FFB still works, it just feels dead.

It's something to do with the GIMX or maybe Drivehub, as it's not the same using a G Pro wheel natively (which I plan to sell, hence getting this all working).

Is this a known thing, any ideas please? Thanks.

This is a known limitation when using Simucube via GIMX/Drivehub on PS5. High-frequency FFB details (road texture/curb vibrations) often get filtered out by the adapter chain, especially at larger steering angles.

larger steering angles have a really big impact survival race

Interesting setup! I've heard of similar issues with GIMX and Drivehub combinations. It sounds like the finer road detail is getting lost past a certain steering angle. Have you tried adjusting the force feedback settings specifically within GT7, and also within GIMX or Drivehub if those allow it? Maybe tweaking the sensitivity or deadzone there could help.
