RBA changing BS will have to be a MTHD thing, it won't be allowed n MT. i agree camera offset distance is too small, perhaps 1000?, i might make a PR. camera offset is not the main cause of stuttering, that happens all the time not every 200 nodes |
| 00:48 |
RealBadAngel |
paramat, im not quite sure if it will be worth it, i keep getting mixed results |
| 00:48 |
RealBadAngel |
but offset indeed could be changed |
| 00:49 |
paramat |
ok |
| 00:49 |
RealBadAngel |
i will play with the issue later on, atm i dont have time for something unrelated to deferred rendering |
| 00:59 |

stutter happens when there is meshgen spike // Captain Obvious |
| 00:59 |
Fixer |
coincidence? don't think so |
| 01:04 |
RealBadAngel |
well, whatever is the reason of updating meshes, it has to be limited, its a pure nonsense having mesh updated because time of day changed, player moved a bit and crossed camera offset change line, etc |

makin mesh is heavy duty stuff and have to be avoided at all costs |
| 01:07 |
RealBadAngel |
atm there are 3 reasons left that are making mesh dirty -> time of day (lighting will fix it), cracks (have to be removed same way as halo), and camera offset (not quite sure how to get rid of it completely) |
| 01:09 |
RealBadAngel |
well, 4. changing any node meta is causing complete up to 7 mapblock meshes regen |
| 01:10 |
RealBadAngel |
with all those 4 issues solved we can enable VBO and go further |
| 01:10 |
RealBadAngel |
at least thats the plan ;) |
| 01:54 |
VanessaE |
RealBadAngel: the camera offset can only be dealt with properly by splitting the world into many (thousands of) irrlicht Scene Nodes |
| 01:54 |
VanessaE |
it's there because the map is one big scene node, and the camera gets glitchy once you get more than a few hundred meters from the camera's origin |
| 01:55 |
VanessaE |
or rather, the rendering precision becomes a problem and it LOOKS glitchy. |
| 01:55 |
paramat |
would 1000 nodes be okay for the offset distance? it should be maximised |
| 01:55 |
VanessaE |
paramat: nope. |
| 01:56 |
VanessaE |
even 1000 is enough to see the glitch, if you're looking for it |
| 01:56 |
VanessaE |
I don't recall why 200 in particular was chosen, though |
| 01:56 |
RealBadAngel |
VanessaE, i was looking hard with offset set to 2k and couldnt find any |
| 01:57 |
VanessaE |
it probably depends partly on the video driver and irrlicht version |
| 01:58 |
VanessaE |
either way, there is only one proper way to fix it. |
| 01:58 |
VanessaE |
the proposal at the time was to make each Minetest mapblock a scene node. |
| 02:14 |
paramat |
i think 200 is a little too low, as it apparently causes mesh updates |
| 02:16 |
paramat |
need to discuss with nore though |
| 02:25 |
RealBadAngel |
not really mesh updates but shitload of operations on vertices adding offseted pos to them |
| 02:27 |
paramat |
ok |
| 02:29 |
RealBadAngel |
if we consider using VBO it will also mean that mesh have to be reuploaded to GPU VRAM |
| 02:52 |
VanessaE |
RealBadAngel: but that doesn't answer the scene node problem. |
| 02:52 |
VanessaE |
adjusting the camera offset is just delaying the inevitable. |
| 02:54 |
RealBadAngel |
im trying to figure out best solution |
| 02:54 |
RealBadAngel |
and im not sure about scene nodes idea |

ok |

Hope 3D plantlike / torchlike is still among them BTW. I think that's a more urgent visual improvement anyway. |

IIRC you got it working with waving plants last time, so hopefully not much is left there. |

Taoki: would having the *thin* drawtypes like signlike, torchlike, plantlike extruded look better? |

funny, i just got an attack of stuttering, it was starting a minute or so after starting game, so even walking was choking. played a bit with camera far plane to see if that would help |
| 15:59 |
Fixer |
and? |
| 15:59 |
RealBadAngel |
it looked like it helped, so reverted all the changes to see if stuttering will back |
| 15:59 |
RealBadAngel |
and i cant reproduce stuttering anymore lol |
| 16:00 |
Fixer |
RealBadAngel, yes, that's the problem, one time i was having very baad stutter with shaders disabled, next day - gone o_0 |
| 16:00 |
RealBadAngel |
fuck me walking if i know whats the reason |

your videocard has clock frequency autochange support? |

RealBadAngel |
havent played with gpu settings |
| 16:06 |
Fixer |
RealBadAngel, sometimes GPU/MEM clocks drop from 1000 to 750 or even 150, for very short time, few times, not sure if it is the cause |
| 16:08 |
Fixer |
RealBadAngel, try walking on this test world -> https://github.com/minetest/minetest/files/101456/Just.Test.zip |

if you can observe stuttering check the clocks then |

if thats related |

| 16:29 |
Fixer |
RealBadAngel, on heavy world, it can stutter when clocks go down to 150MHz for some reason, but there are stutters at FULL clock |
| 16:29 |
Fixer |
hmmm |

RealBadAngel |
https://travis-ci.org/minetest/minetest/builds/108787153 |
| 16:29 |
RealBadAngel |
Fixer, so thats not related |
| 16:30 |
Fixer |
RealBadAngel, hold on |
| 16:30 |
Fixer |
RealBadAngel, it is partially related |
| 16:30 |
Fixer |
RealBadAngel, if stutter is really deep it is clocks going to min for 1 sec or so |
| 16:31 |
RealBadAngel |
Fixer, so related or not? |
| 16:32 |
Fixer |
RealBadAngel, only for some deep stutters, it is partially related, some stutters are caused by frequencies some are not |
| 16:36 |
Fixer |
RealBadAngel, pff, why on earth it lower the frequencies when i load heavy MT scene with 30 fps :( |
| 16:37 |
RealBadAngel |
theres some auto tune code in mt |
| 16:38 |
RealBadAngel |
i wonder if it doesnt work the opposite as it should |
| 16:38 |
RealBadAngel |
first of all, why the hell camera far plane is not set when lowering view range? |
| 16:39 |
RealBadAngel |
and why fog doesnt match view range |
| 16:54 |
Fixer |
RealBadAngel, clock powersaving can cause some stutters, but not a whole lot to account for everything (most of the time MEM clock is at 75% (lol), GPU is at 100%) |
| 16:55 |
Fixer |
RealBadAngel, also, some time clocks going down does not cause stutter at all |
| 16:55 |
Fixer |
RealBadAngel, lots of time actually |
| 16:55 |
Fixer |
RealBadAngel, so it is not powersaving problem only, other sources are at work |

RealBadAngel, just walked, let me eat something, i will test deeper |
| 17:27 |
RealBadAngel |
sure |
| 17:28 |
Fixer |
RealBadAngel, why on earth drop frequencies down to 15% level for very short time in heavy minetest scene? feels like source of the problem is MT, that reduces (?) gpu load for very short time, causing frequinces down and big stutter after |
| 17:29 |
|
ud1_ joined #minetest-dev |
| 17:29 |
Fixer |
and frequiences back to normal |
| 17:29 |
Fixer |
maximum 1 sec for this all |
| 17:29 |
RealBadAngel |
it may be this auto tune code |
| 17:31 |
RealBadAngel |
from quick look it works that way: if it takes too long, lets lower wanted fps |
| 17:31 |
RealBadAngel |
then gpu thinks theres less to do, lower clocks |
| 17:31 |
RealBadAngel |
then mt again lowers wanted fps |
| 17:32 |
RealBadAngel |
until it chockes itself and gpu is sitting idle laughing |
| 17:32 |
RealBadAngel |
pretty funny |
| 17:33 |
RealBadAngel |
also i like the code for trying to be smarter than hardware |
| 17:33 |
RealBadAngel |
far clipping plane is actually disabled no matter what |
| 17:34 |
RealBadAngel |
the code that sets it looks like it could set an actual value |
| 17:34 |
RealBadAngel |
if far plane could be further than 20000 |
| 17:35 |
RealBadAngel |
total absurd |
| 17:35 |
RealBadAngel |
so, no matter what far is always 2000 |

RealBadAngel, in general, with your changes you get little performance boost, but stutters are the same |

RealBadAngel, as you can see both curves on graph #3 became one somewhere near stutter zone (which is at the end - highest spikes) |

RealBadAngel, very slight fps boost, but stutters are the same, so it is not fixing the stutters unfortunately |
