Re: Controller calibration same settings, different feel ps4 vs ps5 controller
DS4Windows by default works by emulating a Xbox controller as far as I recall. It remaps the inputs you give to your Dualsense 4 by emulating the Xbox pad and tricks the PC into thinking it is the latter.
Dualshock 4 and the Dualsense are different controllers with different components.
Considering those two points above, I would never expect settings to feel 1:1 the same when swapping the two back and forth.
Have you considered making two controller profiles in the game?
Anyway, can't see a way out of this that not goes through experimentation.
I have a fine wheel alright, but I rarely bother setting up my rig just to play F1 as the FFB isn't that great and it is way more enjoyable on a controller. Always liked it on my PS4, and came to love it with the PS5. I can't say if the Steam/PC native support feels the same as playing with the Dualsense on the console, but if it does it is 100% worth it in my opinion.
