Instead of using the plugins that lower performance, you can uncensor the game with Special K.
Once you load into the game past the start screen and any conversations with the lady, take out your dick and pause the game and open the Special K interface; you need to pause it as otherwise it will be hard to find the correct shaders.
Click on Render Mod Tools to open the render mod tools.
Open the Vertex Shaders tab
Look for any and all Shaders called "Shader Graphs/mossiac_shader 1"
Click on the shader then click the "Never Draw" box.
Once you have found all of them, close the "Vertex Shaders" tab and open the "Pixel Shaders" tab
Look for any and all Shaders called "Shader Graphs/mossiac_shader 1"
Click on the shader then click the "Never Draw" box.
Then click the "Store Shader State" button located above the Vertex Shaders Tab
Close the Special K overlay.
You will see worse performance while the Special K overlay is open, but once you close it the performance returns to normal.
Not sure if this makes a difference but I also have CinematicUnityExplorer installed via bepinex
