S.T.A.L.K.E.R.: Shadow of Chernobyl

Fixing the Shadow Bug on Windows 11?
My shadows cut between light and dark abruptly. I tried doing the normal fix of setting "r2_sun_near" to 20 and "r2_sun_near_border" to 1 in user.ltx in the Steam directory. It did nothing. What's more, the game hasn't generated any folder in %public%.

Is there a way I can force the engine to accept the change? Is there some simple mod I can download to fix it? I like how the game looks, I just want to fix the shadow bug.
