Ah that's nice!. One Q though- how does that work? I though these cmd line parameters can't be changed in-game, atleast that's what I was told whenever I asked.
That, generally speaking, is the intent. We treat options that the user sets, either through the options menu or the commandline, as imperative; we try to not alter them at all.
But, that's a convention, not a rule; When you enter the lab, the bloom setting you set on the cmdline is saved, and while you're in the lab, it can be altered through that menu, but it will be reset once you leave. The intention here is that you can quickly see what bloom level you prefer, then enter that in whatever launcher you're using.
That said, we do want to do a separate options screen for FSO options (like bloom intensity, shadow quality and such) at some point. That is a separate thing from the lab, however.
