I’m having the exact same issue (Normal 4.26.1 downloaded from the Epic Launcher).
Setting r.Shadow.DistanceScale to 2 does make it slightly better but it still doesn’t go far enough, and setting it any higher doesn’t seem to make any difference so I guess there’s a limit to 2.
I thought the idea of RayTraced shadows is that they can go as far as possible…
Also I feel like in 4.26 the shadows are way noisier than they were in 4.25, I think Epic might’ve nerfed RTX
