I've noticed this too and made a post in the technical support forums. Didn't realize there was this bug forums, kinda new to forums in general. But coming across this post alone has given me some sense of peace knowing I'm not just crazy and imagining this. This wasn't an issue before DT at least for me. I've recently been switching controllers trying new things since the xbox series controller is very loud, mainly the dpad, so wanted to try using a ps controller since I started on ps4 and was a bit familiar with them. I've always used controller. And I will confirm this issue is not on the ps4 controller or the xbox series controller; I only see it on the dualsense.

Another thing I wanted to mention, not sure if others have noticed or if this is somehow specific to me, but the ps5 analog sticks themselves seem to control differently than other controllers. Simply running in circles without moving the camera you can see your character seems to run in a more square shape, vs other controllers where it's more rounded. And if you do it slowly you can see there seems to be less variable inputs between the cardinal and intercardinals, like they hug those more. If you walk forward and slightly tilt to one side your character hugs that forward cardinal until you get more to the intercard of the analog. You do this same thing on a ps4 or xbox controller and there are more micro adjustments your character does.

Honestly I think they did something with steam integration in the game to make ps controllers "better" but it's weird it's only with the ps5. I only say this because I remember reading up another forum talking about the opposite, wanting to get that more dpad like movement from the analog stick and steam integration can do that.
