sfan5: regarding https://github.com/luanti-org/luanti/pull/16265: the real performance advantage arises from avoiding garbage collection in instances where luajit cannot sink the created table |
| 03:15 |
repetitivestrain |
i cannot offer you any benchmarks, but the jit compiler cannot compile branches that begin in blocks with large numbers of live stack slots, which applies to some of the mcl_mobs pathfinder, nor can it sink values across traces |
| 03:15 |
MTDiscord |
<jordan4ibanez> Reduce, reuse, recycle |
| 03:16 |
repetitivestrain |
Mineclonia has been extracting get_node_raw from core.get_node with debug.getupvalue for some months now and in my experimentation it consistently reduces the frequency at which the garbage collector is invoked and the duration of globalsteps that coincide with garbage collection |
| 03:18 |
repetitivestrain |
i very much suspect kno10's benchmark is one where LuaJIT throws in the towel |
| 03:19 |
MTDiscord |
<jordan4ibanez> Were these tested in singlenode? |
| 03:22 |
repetitivestrain |
get_node_raw doesn't concern map generation but rather pathfinding |
| 03:23 |
MTDiscord |
<jordan4ibanez> Wat. I'm saying for the benchmarks. Best to not have any variables when bench marking |
| 03:24 |
MTDiscord |
<jordan4ibanez> Generate that one node and hammer that same memory address with no interference to see which one wins, etc |
| 03:24 |
repetitivestrain |
those _macro_ benchmarks were conducted in the same map and at roughly the same coordinates on a real server with an essentially constant number of mobs and 2-3 players |
| 03:26 |
MTDiscord |
<jordan4ibanez> I'm not talking about your benchmark, I'm talking about the original 15-20% ones |
| 03:26 |
repetitivestrain |
You'll need to ask kno10 |
| 03:33 |
MTDiscord |
<jordan4ibanez> There is also another performance implication. You can reverse a lookup with a table of predefined IDs as a set and if it contains, you have hit something you're looking for. But also, you can precache a single so it's just a number to number compare. If it's okay, etc |
| 03:34 |
repetitivestrain |
table indexing can easily account for the 6% difference observed by sfan5/SmallJoker |
| 03:35 |
MTDiscord |
<jordan4ibanez> I wonder if this is actually faster to use, via precache IDs in a group via a numeric table key to numeric value to out pace checking if a node is in a group from the standard api elements |
| 03:37 |
MTDiscord |
<jordan4ibanez> local gr = idt[core.get_node_raw(xyz)]; print(gr and gr > 0) |
| 03:38 |
MTDiscord |
<jordan4ibanez> But that's not correct, it's a multi return, but I'm too lazy to fix it |
| 03:40 |
MTDiscord |
<jordan4ibanez> So basically you'd scan the registered nodes on mods loaded and dump the group you want in via the ID so the heavier work happens at load up |

try this benchmark: both generate traces of the same character, but the jit compiler cannot sink the table created in core.get_node across a stich (pr:next), the trace which is stitched and its side trace, with the result that a real table is allocated and dereferenced in all three cases |

!tell Bracket try using the "restore default settings" option in the bios boot screen. It should be f9 according to this old forum post. If not leave the both the cmos and laptop battery's out for a day and after hold the power button for 30s to drain every drop of juice and check to see if that help remove the power from the memory chip. |

@luatic, take a look at the gltf morph target PR when you get time. I believe that it won't work with the usual Blender workflow without the "KHR_texture_transform" extension |

@luatic, afaik blender shape keys are only meant for shape changes and it appears that texture/UV animation is done mostly/only by redoing the logic on the game engine side |
| 22:18 |

so my request here is non-standard and would make Luanti special if implemented |
| 22:22 |
MTDiscord |
<luatic> i know :> |
| 22:23 |
MTDiscord |
<luatic> i also have an ulterior motive for getting this into the engine: i need a sequel to "bad apple but it's a b3d", and what would be more suitable than "bad apple but it's a gltf" for that? |
| 22:24 |

I don't get it but I approve |

worst case scenario I will hide 10 face variants into the head |
