Go try the tweaks over in the "Compendium of Tweaks" thread, and if that doesn't help (And it likely won't, I still firmly call placebo), then sadly you just have to join the rest of us who have come to accept it.
It exists because of the engine and middleware implementation, and there's really nothing we can do about it. Its been yelled at CDPR enough times that if they aren't already actively working to fix the issue, then it's simply something that's never going to be fixed. It sucks, it annoys me just as much as you, but we just have to deal with it, and if it's something that really severely hampers your enjoyment of the game, then I would in future be weary of CDPR's products since they'll also be using the same engine (And likely middleware also).
