Worldsfactory has a new quote from Lords of the Fallen developer Michele Giacalone about why they dropped support for the PS3 & 360 versions.
More information."Switching to next generation was one of the biggest challenges for this project. We had to find our definition of next generation in term of visual quality and scene complexity with basically no experience with the new hardware. This was a crucial phase because we had to base on that the new guidelines for artists and designers, affecting the whole content creation process. The more we progressed with porting our engine to the new consoles, the better we could adjust those guidelines trying to find the right balance of visual quality, scene richness and performance. Moreover, in order to achieve the best performance on the new hardware we decided to not maintain back compatibility with DirectX 9 and previous generation consoles. For example we dropped completely our deferred lighting renderer – necessary on the Xbox 360 – in favour of a full deferred rendering approach saving a nice amount of time in draw calls. Getting back to the question, we couldn’t have achieved such result on the previous generation hardware."
