I've put together a test ReShade configuration here, adding effects to the fifth game such as "Adaptive Texture Sharpness Enhancement," "SSAA" (Screen Space Antialiasing, basically advanced anti-aliasing), and "HBAO" (Horizon-Based Ambient Occlusion, a very clever ambient occlusion system that greatly improves the visuals).
You can see the screenshots here: http://imgur.com/a/iRALt
In terms of PC performance, this really hits hard, but I think I've managed to achieve a balance between image quality and speed.
And yes, HBAO requires DirectX 10, and even better, DirectX 11.

Extract it to the bin folder. Before using it, disable anti-aliasing in the game. The configuration is enabled and disabled in the game using the Scroll Lock key.
