wait can anyone run other stuff with DF?
I don't doubt they can.
I'm currently 'grinding'[1] an Adventurer in DF on a home machine where (for some reason[2]) it's between 3 minutes and 5 minutes between movement or 'tick-worthy' action (moving the "look" or "throw" cursor around is normal speed,
actually throwing something means the long pause before "I have control again" the same as with moving to an adjacent tile), as the nominal "100 (40)"-ish FPS indication drops down to "0 (0)" until suddenly it zooms to "400 (??)"-ish (before throttling back to the cap of 100 again) and then I'm back in the room. DF is rushing it's little legs off (and the case/CPU fan noise goes up a notch or two, although not as high as it
could go) and certainly doing
something.
But (and with no sign that this slows down DF's meditations at all) I've been able to both watch video files and even render 3D scenes (the former might be mitigated by the graphics card, the latter won't be) without noticeable slowdown from when I don't have DF running. On a single-core processor[3]. As it's an off-line machine, I haven't tried connecting it up to Youtube and seeing if
that's affected.
However, the comparison was between Youtube video playing and a telnet session, and the latter is far less intensive of both network connection (at least while Youtube buffers as quickly as it can) and console power, is all I was saying. And far less (internally) than DF in unpaused Fortress mode, as well.
Just to make what I was saying a bit clearer. (And it's been a few versions since I've personally noticed DF prevent
any other program progressing accordingly, in the background, as well as in the foreground when DF is backgrounded, though I have seen
some performance hit.)
here is a picture of a cat made of pizza.
That's not
just a cat made of pizza. It's a cat made of pizza
IN SPACE!!!![1] Not as in "spamming skill-increasing stuff", although I am sneaking (but already Legendary at <foo>/2000, by now, and only sneaking to avoid too much conflict with aggressive wildlife, not to train)
[2] I'm speculating it's because of too much wildlife, possibly even unseen cavernlife (every now and then I've had "The Reacher is no longer enraged" notifications), moving around in the immediate vicinity and causing a lot of between-turn calculations to take place. Either that or somewhere
just out of sight there's a worldgen glitch with massive liquid movements happening (but I'm getting no cave-in messages). Either way, I'm hoping that when I've scoured this location (a cave that had a now ex-werebeast, and a bandit camp with a now ex-bandit leader (probably killed by the werebeast, as with most of the rest of the bandits) for valuables I can walk away from the location and get my FPS back again. Or find out what's causing it, perhaps, and deal with it if it's yet
more packs of dingoes hogging the movements calculator. (I'm rather stocked up on dingo meat, already.)
[3] Maybe it's XP's multitasking priorities gone awry, but it doesn't appreciably lag for any other aspect of DF, just this one Adventurer that I don't really want to abandon if I can help it.
