Well, I decided to try 0.4.15 (the most promising-looking version I had sitting around) on an old XP box with a Transmeta Efficeon and Radeon VE - it actually runs kinda playably if I turn the settings _way_ down, about 10 FPS. |
| 02:44 |
erle |
cheapie why would you have to set it *that* low |
| 02:45 |
cheapie |
It's not real happy (lots of warnings in the logs, seeing as how the card only supports OpenGL 1.3) but I haven't actually seen any incorrect rendering. |
| 02:45 |
erle |
how old is the computer anyway |
| 02:45 |
cheapie |
Those are parts from about 2002. |
| 02:45 |
cheapie |
And not even good ones for the time either :P |
| 02:45 |
erle |
try the irrlicht demos on that hardware please |
| 02:45 |
erle |
i wonder if it is because minetest renders shit or because old hw |
| 02:46 |
cheapie |
Do you have a link to the demos you want me to try? |
| 02:46 |
erle |
cheapie the one with the dwarf and the dynamic shadows and the particle system, wait i look for it |
| 02:46 |
cheapie |
(and note that The Sims 2 runs at about 2 FPS on it in 800x600, so the old hardware is almost certainly most of it) |
| 02:47 |
cheapie |
Just looked up the dates - CPU is from 2003, GPU is from 2001. |
| 02:48 |
erle |
cheapie, this one https://github.com/zaki/irrlicht/blob/master/examples/08.SpecialFX/main.cpp |
| 02:48 |
erle |
are you sure you are using openGL and not software rendering? |
| 02:49 |
cheapie |
It is using hardware OpenGL. This performance is expected for hardware like this. |
| 02:50 |
erle |
i have played earth 2150 on a system from 1999 |
| 02:50 |
erle |
i think it can be done better |
| 02:50 |
cheapie |
As far as the demo goes... I don't see a precompiled version on there, and compiling anything on a CPU like this would be... painful, not to mention that it's currently running Windows XP and I would have to get the development environment working on that if I wanted to do so. |
| 02:50 |
erle |
maybe it is windows? fleckenstein once tried minetest on the same hardware i use (thinkpad T60) on windows and found it was unplayable |
| 02:51 |
erle |
of course you have to compile the irrlicht sdk |
| 02:51 |
erle |
it will not take more than an hour i think |
| 02:51 |
erle |
faster with -Ofast or so but then you get a slower binary |
| 02:51 |
cheapie |
...keep in mind what CPU this is. |
| 02:52 |
erle |
well, i have no idea where there are precompiled versions of those things |
| 02:56 |
cheapie |
I'll probably be trying Linux on it at some point eventually to see how that runs - if I do, I'll try out MT on there as well and see what happens, but don't expect much :P |

Why does minetest hold so much in memeory after leaving a Multiplayer server? |
| 15:03 |
independent56 |
https://i.imgur.com/6kocfII.png |
| 15:03 |
independent56 |
The first drop is me leaving the server, the second me closing the client |
| 15:04 |
independent56 |
what is it? (i know why; reduce future loading times in the same session) |
| 15:14 |
|
independent56 joined #minetest |
| 15:15 |
erle |
sfan5, oops thanks. but why would i ever want unsafe math optimizations? |
| 15:16 |
erle |
independent56 i doubt this reduces loading times, i think it is just an artifact of not freeing memory right away. |
| 15:16 |
independent56 |
Hmm |
| 15:17 |
independent56 |
I've once left Minetest idle to watch Youtube videos and then i look and it's still the same high memory usage |
| 15:17 |
erle |
you can join and leave different worlds. does the memory footprint rise each time? if so, memory leak. |
| 15:17 |
independent56 |
Hmm, i'll try that |
| 15:20 |
independent56 |
Does not seem to |
| 15:21 |
independent56 |
But on rejoining my server, load times seem to be decreased slightly |
| 15:21 |
erle |
how nuch |
| 15:26 |
independent56 |
I'm not sure |
| 15:26 |

How do i close iron doors automatically as a mesecons signal turns off? |
| 16:36 |
Krock |
have you tried turning it on and off again? |
| 16:42 |
Krock |
if you need two positive edges to trigger it, you could use a delay circuit to multiply edges |
| 16:45 |
independent56 |
I have, by walking on and off a presure plate |

<Jonathon> or use at_sync_ndb to get rid of the ghost tracks |

No |

"is there a way" yes |

valuable advice: there is always a way, but often enough it is not feasible |

independent56 |
ugh |
| 17:52 |
independent56 |
I guess i'll have to learn SQL |
| 17:53 |
sfan5 |
there's no sql to learn, minetest uses the db as a static key-value store |

it's feasible |
| 17:54 |
MTDiscord |
<luatic> It isn't. Unless there are some good libraries for dealing with MT's map format. |

Just make backups next time, fam. It's always worth it. |

there might be one in go |

definitelya, i have, but they're approaching 12 hours age |

Hmm, seems smart until you realise i make maps at 04:00 in the morning, way before i spilt my heart into a factory and level crossings |

BREAKING: Super glow glass found to contain "copious" amounts of Uranium according to scientists |
| 18:54 |
|
ronoaldo joined #minetest |
| 18:58 |
MTDiscord |
<luatic> Doesn't Uranium usually glow green (i.e. a single wavelength or a couple discrete wavelenghts)? The yellow light super glow glass seems to emit on the other hand is a continuous spectrum like that of a light bulb, containing pretty much all wavelengths. This doesn't necessarily exclude Uranium as an ingredient, but Uranium decay as the only source of the spectrum is next to impossible (unless the glowing comes from the glow glass being |
| 18:58 |
MTDiscord |
heated as the Uranium decays). |
| 18:59 |
sfan5 |
does uranium glow at all? |
| 19:07 |
independent56 |
Hmm |
| 19:07 |
independent56 |
Maybe the world is constantly struck by UV from the sun |

muurkha |
also in general solid-state things and glasses tend to have much wider spectral line widths than gases |
| 19:32 |
muurkha |
are you looking at a spectogram of this super glow glass? because you can't really tell by looking at a glow whether it's a continuous spectrum or just two or three wavelengths |
| 19:32 |
muurkha |
if you have uranium in something then after a few million years you'll have the whole uranium decay chain, and some of the decay chain elements are a lot more active at stimulating phosphors (such as uranium oxide) than uranium itself is |
| 19:33 |

uranium metal doesn't glow at all (unless it's incandescent, of course) |

take a look at spectra of "white" fluorescent lights and LED bulbs online, for example |

they're not "white" in the sense of being a continuous spectrum but you can't tell by looking at the light |

sometimes you can tell by looking at things illuminated by them because they look the wrong color |

If you fell and somehow landed in a boat, sitting and ready to control, would you sustain fall damage? |
| 22:01 |
MTDiscord |
<luatic> independent56: If you mean right-clicking the boat and receiving the attachment command before you hit the boat: Yes. Since there is no proper clientside prediction though, there's a decent chance that you die attached to the boat. |
| 22:01 |
sfan5 |
attaching somewhere erases velocity |
| 22:01 |
independent56 |
hmm |
| 22:01 |
independent56 |
Thats why boarding a train at full speed doesn't kill me |
| 22:01 |
MTDiscord |
<luatic> BTW sfan5: Why are only a select few player properties serialized? I find it out that current velocity isn't serialized. This allows evading death simply by rejoining. |
| 22:01 |
sfan5 |
not sure I get luatic's comment about clientside prediction, fall damage is entirely client-side |
| 22:02 |
sfan5 |
dunno |
| 22:02 |
MTDiscord |
<luatic> find it odd* |
| 22:02 |
sfan5 |
oh actually here's the reason: there's no way to give the client its velocity back |
| 22:02 |
MTDiscord |
<luatic> But there is with add_velocity |
| 22:02 |
sfan5 |
that's recent |

sfan5 |
hm |
| 22:03 |
MTDiscord |
<luatic> sfan5: Yes, that's the point - there's no proper clientside prediction for the attaching to the boat, so the server sends the attach command, you die of fall damage, you receive the attach command. |

oh, that |
