ive seen too many ppl complaining about not knowing how to use RT or help explanations not comprehensive. come on, why not to try out the settings and learn by yourself? of course if you cant understand the description of a setting the problem is about u, not the software; so go look for some information on it. systems r almost always unique and settings use to work different to each one and there is still a personal taste about more img quality or performance and stuff - its not difficult to find out comprehensive information about drivers features and settings at all, and it will still be better than any answer for "how do i set mipmap LOD bias" or something. in the end you will be better answering than asking anyway.
Before R7 help for RT settings was really necesary. However I find the context help to be just fine. If it lacks something it may be some clear texts (aka for newbs) like :"this setting must be 1 for quality and 0 for performance".
