Hi guys. I made a few improvements to the demo renderer, the most recent being the ability for a person submitting a demo to be able to set certain cvars for the renderer. For instance, being able to render a demo with r_picmip 3 rather than 0. My question for you guys is:

What other Q3/QL cvars should be exposed and allowed to be changed?
What values for the cvar should be allowed?
If you know, a quick description of what the cvar is/does.

I'm mainly looking to cvars that will get a fair amount of use, rather than an obscure cvar that will be ignored by most users.

FYI:
Q3 renders use q3mme
QL renders use wolfcamql
Any cvars that either of those two engines use are valid.

Note that the cvars can be mod-specific, like for cpma, defrag, etc.
