@HoBGoBLiNzx3, The OXR Toolkit is optional really. The OXR Dev Tools gives you the resolution options, MR on/off, which I use on always. And the OXR version of 3Dmigoto gives you sharpening, the haze reduction, color enhancing, and more. I am using the OXR Toolkit, but almost using none of its features now. I could even not use it at all since setting up 3Dmigoto...
Some others may weigh in on how they use both to achieve more, but perhaps you don't need it.
