My client wanted graphics that matched their concept arts and ideas more closely. Their goal was to get it done with the least amount of work from their art team possible (no reworks on models or textures).
I've built the shaders and graphical solutions for the project, which upgraded the outdated look to an up-to-date version.
Part 2 was performance optimization on both the graphical and c# code side.
At the end they got much better (30-80%) performance and also higher graphical fidelity.
