There seems to be an incompatibility with this version of ReShade and
Assassin's Creed Unity (DirectX11 64bit application). The game plays fine but ReShade is not loading at all.
Here's a log:

Tell me if you need more info.
EDIT: last version of ReShade that works with this game on my PC is
0.11.4.636.
