Well it's quite an old thread but i started with SH3 a few days ago and am now learning manual targetting and i have the exact same problem, the 1.5km Overlay is offset to the east and the distances are a little wrong. Like HellBlaz3r I have a ti4200, with newest drivers. No other Mods installed.
Does somebody have an idea ? I couldnt find the 3km overlay anywhere, does somebody know a downloadlink where I could get it ?
I'm using Jase's overlay now, better then nothing, but this one would be simply great
