I did some more trying out and neither running with steam shut down or running through steam fixed the issue. Running without steam and DS4Win, the game didn't recognize the controller at all. All the other combinations of Steam and DS4Win had the same aiming issue. But I did discover that going to stationary aiming mode will lock the aim down. You can still aim to 45 degrees in either case though. And I kinda feel your pain if it's in the engine and not in your hands... I'll try mouse&keyboard, that's the way I played the 2019 demo way back when, which I really liked.
