Very slow framerate?
« on: October 29, 2007, 06:30:00 pm »

I'm running on a 1.6ghz with 1 gig of ram and a good video card and with the starting 7 dwarves it regularly goes as low as 15-20 FPS. Is this going to be normal? I have weather, temperature, vsync all off, changed the fps settings and window size, nothing affected it. In the menus it goes up to 100 fps.

Is this going to be a permanent thing or do I have to go back to standard DF to get my usual 100+ framerate?

The framerate I get in Adventurer mode is even more horrendous; 1.4Ghz, 512mB RAM, decent video card. (Edit: As for how horrendous, I have to wait several seconds to move. This is Weather/Temperature/VSync off- I think I'm just outdated...)

I think DF has evolved past me. =( Seeing as how my rig is celebrating its seventh aniversary.

Adv mode really slow in towns. Seems to be even worse if you have companions. Outside it is more tolerable, but still slow when there are many monsters nearby. Hopefully some optimisations will be made.

Allow me to note that I wasn't complaining or anything; just sorta depressed that my computer is so outdated, that's all. I'm very appreciative to be able to play the new version. =)

What's odd is I get the same framerate now in DF as I get in 3dmark06. That's...insane. My system isn't top of the line but is by no means old... athlon x2 3800+ (dual 2ghz cores each with 512KB L2), geforce 7900GS/OC 256MB 256 bit GDDR3 w/ PCIe, 2x512MB PC3200 DDR DIMMs in dual channel mode.

Some observations. I started a fortress on a flat bit of land, and started digging down. I get 100fps while viewing the surface layer, but when I move up or down the z axis it drops to 20ish. But it's always 100 on the surface.

Also, I don't remember if it was like this in the older versions, but if I have the list of commands open I get about 5-10 more frames per second than if I have the entire window be the play area. This would make sense if the game had to draw complex graphics... but just a few simple tiles less to draw and the FPS increases by 10? Crazy!

well 3dmark uses your video card, DF does not (not to any real extent, anyway).

I have an athelon 2000+ (I know, old) and 1 gig of ram (don't think that really matters much) with temp and weather off I get ~50 - 60 fps with the default starting area size and just 7 dwarves. Much slower then before, but tolerable, if just barely. I doubt I'll ever want more then a dozen dwarves or so.

Weather seems to be a big savings, as before. Temp did not tank my FPS very much so I might turn it back on.

Toady has said picking a smaller starting area helps FPS alot, so after I mess with this one a bit I'll probibly try a very small starting area and see if that helps at all.

Edit: I seem to have Ghor's problem as well, I get ~50 - 60 fps on the surface, but when viewing subterranean levels it dips down to ~25 - 30. ouch.

Edit2: creating a food stockpile to move everything off the wagons dropped me down to ~20 fps. Ouch. I might just have to go back to the old version  :(

If anyone manages to get a good fort going; 50-100 dwarves, please tell us your thoughts about speed!

If I had to take a guess here, I'd say all of the speed issues come from Pathfinding. As I use a computer that was found in a sunken Roman ship ages ago, I noticed significant slow down after telling my idle dwarves to build a statue, dig a hole and chop at some trees.

EDIT: 5-15 FPS on average for me, Weather+Temp off. Hot damn. That's the exact same frame rate I got from playing Neverwinter Nights at 1.4ghz, 256mB RAM, 16mB Ati Rage Ultra. =P

Running on a 3GHz, 512MB computer, and I also get slow movement in adventure mode. I also noticed that sleeping takes forever in adventure. After about 10 minutes of waiting for sleep to end I gave up and killed the process.

Hmm.  It seems much faster than the previous version did for me.

Ahhh, it does help a lot of you make the map size smaller. Hit SHIFT-M and -H when you're selecting your location, a 3x3 grid makes me hit 70-80 fps instead of 15-30.

I am running about 1/4 the size of the leftmost screen, and get quite low rates.

Ah, sorry, I thought you meant the video tests. I've not bothered with 3dmark in some time (I know my computer is junk without it telling me   :p) so I don't know what all it has.

See the edit, that's on the surface I drop somewhat when I view lower levels.

I'm also getting the deal where it drops to 25-30fps underground, but is a reasonable speed above ground. ???

edit: It also drops to 25-30fps if I raise the viewing level up into the sky, even though I haven't built anything up there yet.

Thanks for the map size advice, I will try that.  I'm using most of the selectable area (not all) and getting 25FPS.  AMD 4400 so and so ;p  I did notice things get faster when I moved my view to the surface, but that's only when it's paused!

The geography is as cool as I expected, digging down through the mountain to reach "sea level" is pretty fun.  Slower start than when you know where the river is, and don't have to dig down to it ;p  I think I'm going to venture out with more miners and picks this time.

EDIT:
Yeah, going with the default map size put me near the FPS cap.  Default Map size couldn't be considered tiny, I think its smaller than original DF but I don't recall,  its been so long ;p It looks like I got a bunch of clay where I thought there were stone mountains, dwarves angry!!  But I'm appreciating the stone more  :)  With all the Z-levels, there should be plenty.

Dwarves have fallen in my channel, but now they can just dig ramps to get out ;p
