Improve (or, well, at least arbitrarily change) the descriptions of various settings in the graphics options.

More than a few of these have annoyed me for a while, what with their typos and odd wording and occasional lack of important details.

Criticisms welcome. I mean, as long as it doesn't devolve into MORE bikeshedding. Even I don't enjoy that.
I don't think the "much more flexibility" bit is needed, and it's fairly vague.  Maybe just tack on the "much slower" part...
