I installed the mod exactly as instructed on the Steam community site. Unfortunately 3/4 of the screen is now black. See screenshot below. It only starting doing this after installing Special K. Please let me know how to resolve. Thanks.
That version uses Special K’s old waitable swapchain implementation, it does not support changing resolutions.
You should consider replacing it with the latest version.
Also, be aware that the motion blur / depth of field removal code does not work with the latest patched version of the game :-\ You will need to roll-back to an earlier Steam patch.
