I'm also getting some fatal errors if I patch to 1.03. If I return to 1.00 the game falls to about 15fps during gameplay in OpenGL. I'm assuming this isn't normal?
In any case here is the log for booting the game clean and into the first level where I'm getting 15fps:

Running the game on 1.01 with the Wallace DLC installed still runs the same way (in-fact I think load screens might be a bit faster) but Wallace is not a playable character. Here is the log for that:

Finally, patched to 1.03, the game launches but gets stuck at the autosave warning screen, the log starts going mental with the same error repeatedly. This happens with or without the Knives DLC installed.
Edit: My bad, switched to LLVM and ASMJIT and now the framerate is smooth as butter. Still having trouble getting the DLCs to work though.

(Imagine those last lines stuck in an infinite loop.) I don't know if the FPS issue I'm facing is a seperate problem or not, if it is could someone tell me what I did wrong? Hopefully those logs are helpful somehow.
Edit: My bad, I didn't set the recompilers to LLVM and ASMJIT. The game plays smoothly now and I can get Knives playable along with the extra DLC modes but Wallace remains locked away along with the non-functioning 1.03 patch.
Edit 2: Well damn, under my new settings 1.03 DOES boot but only to the menu screen. As soon as you try and get in-game it'll crash and start posting the same errors as before.
