Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Before this update, I never had problems with lag, but since updating, lag has strongly increased. The nether is practically unplayable now.
Lag has stongly increased in 0.71.0to Lag has strongly increased in 0.71.0Agreed, I have almost Absalutly no idea what the problem is.
I've been experiencing this issue for what seems like a while, "unplayable" describes it perfectly. I've fixed it to some extent by disabling all mob spawns in the Nether, but it's still noticeable.
Why does this happen? Is it due to block ABM's, or something nether-specific? I experience this unplayable lag both on the MineClone2 dev server and my modded server.
Server searches good place for spawn point.
Villages generate.
Dungeons now use nodes. As result - they appeared but VM way was faster, obviously.
Structures call emerge_area() before placement.
--- It was by me. But it's all mapgen-related. So if you fly around and return to original point - all these things should stop affecting the lag after several seconds.
playerplus requires more network packets.
Maybe something else. Really lots of changes.
Why not to show your
/profiler save
?This is my
/profiler save
from a fresh server hosting plain MineClone 2. Lag seemed tolerable, until I got close to and killed a pigman and wither skeleton. At this point, sprinting didn't work at all.Hm that's weird. I play on a raspberry pi 4 (which is really not the best PC to play mcl2 on it) and I have no lags.
Not even in the Nether (0.71)
I have similiar issues.
As soon as someone moves around the server goes to 100% CPU, since 71.
And even on my Desktop PC(i5/16GB RAM) in singleplayer iam able to catch up with the mapgen(ie running into a invisible wall with no blocks behind it for a few seconds).
Same with a unowhy Y13 (celeron with 4GB ram).
I had a rational lag with 0.70 (my pc isn't really made for gaming...), but with the last git version, ABM are always partialy skipped, fps drop sometimes to ~10, lava solidification takes about 2-3s and blocks I place sometimes diseapered. (in singleplayer!)
But I had to say, on another more powerfull computer, I tested mcl AND mc 1.16 and....
Trust me.
I think the problem here is server performance rather than client performance (Even if they run on the same computer the cpu time should be shared about equally between threads)
Could you test with my last changes? I hope it will reduce lag.
I agrre i am playing on mineclone 2 71.0 on minetest 5.5.0-dev i minimised the tab and got 15-30 fps
on raspberry pi 4 4GB
1.5GHz Processor
128MB ViDEocon VI GPU
This is not an FPS issue. This is an issue related to network lag.
If this issue is solved, would it possible to release a version 0.71.1?
That way people don't have to wait until 0.72.0 to have a version with a playable nether...
Um... I thought the lag was fine in 0.71.
It might depend on the server, but I am not able to go to the nether anymore, so I can't get glowstone for my builds anymore for example. Before this update, I've never had noticeable lag in the nether.
@seba what about the End?
The End has seemed fairly lag-free on my server, although I haven't tested it on the MCL2 dev server yet.
In the End, it's fine for me.
