reclaim the lag

Yes you can type ingame:
/FeatureFadeDistance distance_number (distance from point of view where feature start appearing faded)
/FeatureDrawDistance distance_number (the distance from point of view where feature fully appear)

You can also use a widget I made to change this and other detail options handily
It is Fov.lua
It need -HasViewChanged.lua and -OnWidgetState.lua
You can find them at https://github.com/Helwor/Hel-K/tree/main/LuaUI/Widgets

how to install local widgets:

widgets in general is just an UI things. It doesnt change things for any other player than you. What I just gave is just an graphical option. Wrecks are still reclaimable.

Would be nice to know what exactly causes lag.
Is it the rendering or simulation performance that degrades?
Does this apply to both Wrecks and Debris?

If the performance hit is high enough, then one solution could be to slowly merge adjacent Debris to reduce number of instances.
Unrezzed Wrecks could also slowly degrade to Debris so that it too can assimilate.

wrecks are units i think so i can disable them but i guess that just stops me building them and i already cant build them

i already tried entering the heap names in the disabled units list =P

its ok though this would be a rarely used feature

Wrecks do degrade pathing speed, as every new wreck causes pathing map to be updated. Solution is to get good and reclaim wrecks.

dont use this it causes memory crash i have a fix but ill test it before i post it

scratch that ill just post back here if it breaks

this seems to work so far...

for name, ud in pairs(UnitDefs) do
if ud.featuredefs then
for _, wd in pairs(ud.featuredefs) do
if wd.object then
wd.object = [[emptyModel.s3o]]
end
end
end
if ud.featuredefs then
for _, wd in pairs(ud.featuredefs) do
if wd.blocking then
wd.blocking = [[false]]
end
end
end
end

no more lag and it leaves the reclaim on the ground but its hard to find because its invisible

combined this with another unit tweak that goo eats metal..

[Spoiler]

the result is effectively no reclaim

and here is a mode if you want to try it
