I have a copy of Arx Fatalis I got years ago, and I recently learned about the existence of the 1.21 patch. I applied it, and it certainly helps with some technical issues I had with the game. Unfortunately, it also introduces a problem I find most annoying, namely that the HUD and UI elements no longer scale up to fill the same amount of space on the screen. I put together a picture illustrating the issue: http://i191.photobucket.com/albums/z285/Crowley9/ArxUIbug.png

Does anyone have ideas on how I might get this back the way it used to be? I also tried Arx Libertatis, but it does not change this aspect of the game.

You can try lowering the resolution to 1024x960, as apparently that's when the HUD scaling kicks in according to the patch notes. No clue really though, i've never tried to fiddle with it.
