An idea:
A dynamic limit like: you will have 0/0 with no one around X radius but
near a Player you might have 10/20 or 20/30? with (say 20 or 30 limit set)

Idea for "Invisible Synced 3 Main Characters":
Have some suggestions as substitute models for 3 main characters (for synced NPCS only, non-Player), (instead of being invisible), any out of these will do:
Substitute for 3 main players:

Franklin:
a_m_y_beach_03
g_m_importexport_01

Mike:
s_m_m_movprem_01 (or cs_movpremmale if "s_m_m" doesnt Work)
s_m_y_devinsec_01

ig_sol

Trev:
s_m_y_blackops_01
s_m_y_baywatch_01

Questions:
Why is it that if the Ped limit is 10-15, other Players can see 2-3 peds, 30 they can see about 5-6. So what happened to the other 25 (or 8-12) Peds, are they redundant? (If the Ped Limit could be exact like 10 ped lim = 10 ped shown, it would be interesting to see what would happen)

It depends on what version the other players are using. With release/nightly if limit is 30 and there are 3 players, they will see only 10 of yours. With test5 above, if limit is 30, other players should see 30 regardless of how many players, but only mission entities are synced. With test6 below it's the same as test5 except that all NPCs are synced, not only mission.

"test6" version log 1:
Default 20/30:
-70 FPS diff, Server with 12 players, a Player nearby got 9/20 while
mine is 31/20, FPS in 30-40
- Vinewood Poppy Intersec, FPS in mid 40
- Lil Seoul, Franklin Agency, FPS in hi 20 to 30, 66 NPCS total, mine
was 31/21, at some point 2 players got about 10-12 ped

- LSC (Los Santos), 3 players near, 7 me, 22/19,30/20,10/19,30/20
for 3-4 others, FPS in 20s

- Weirdly, then the Mod just disconnected and pressing F9 didnt
show the menu, i cant pause either.

Changed to 1/1: FPS diff -25 FPS same server about 9-10 players,

FPS near Player was in 50s,

Asked 1 player, he said he saw 1 cop from my World.

Mod disconnected again, i dont know why

I got these in the ScriptHookLog:

"test5" version log 1:
Testing 5 due to test6 disconnecting, unable to pause/re-load game
20/30
Airport, 3 players around, Repeated Plane crashing, then the game
crashed. FPS was about 40-50s at first then 30 then it crashed
Some player got about 20-30 synced at that time.

Luxury Heli can't get u in as passenger, you will just hijack
the driver, also same with Bikes

1/1, Airport, FPS now in 90s

Tried 100 and 1 Ped limit, with a Player, he said he couldnt see Cops from
my world in Vinewood

20/30
Tested with another player Paleto, his sync was 3/20, so he might see
about 3 peds? Asked him but he only said "some"

@oldnapalm
An idea for "Dupes peds":

https://docs.fivem.net/docs/game-references/ped-models/

Some of these duped NPCs are classified as a code like: "Scenarios" (s_f) or "Story Scenarios" (u_f) or "Story" (ig_) or have specific model code like:
Example :
s_f_y_bartender_01 (Strip Club Bartender, duped)
ig_wade (Wade in strip club or in missions)
mp_m_shopkeep_01 (Convenient Store clerk) Specific code (it is labeled MP despite existing in SP)
So maybe if they can be "tracked" so that only 1 version is visible (Like removing the sync dupe via model name for example)

With tests 5 and 6 the limit must be lower, because it's per player and not divided between all players (30 on a server with 10 players can add 300 synced peds which will surely drop FPS to the ground).

This test is the same as 6 but without the number of synced entities in player list because it seems to be what is causing the crash.

"test7" version log 1:

Default 20/30: FPS 20-40 near idling Player, with 2nd
Player coming in with bunch of cops

5/5 near 1 Player, in Hospital, only saw 1 cop in 1 car

5/5, near 1 player, 5 wanted level, about 10 cops, FPS in low 30

Teled away from him, but there were 2 cops in his location still
when i teled back to him (Note 1)

Strip club intersec, about 10 cops on ground, 2 helis, FPS in hi 30
to 40

The Cop ped of the guy who tele to in (Note 1), still appeared on radar.

I was near Tranny bar with 2 guys, it had a few cops, i teled to
Rockford Hospital, there were still 5 cops in that place

Hospital had 13-15 peds on ground, 2 helis, FPS in mid 30

Teled from Hospital to CJ street, 3 cops are still on radar in the
Hospital

Army base, 2 players near, from 5/5 to 1/1 got about 8-10 fps gain
(35 to 45) There were about 17-18 Military peds

Sandy shore hospital, 2 players, about 11 ground cops, 2 helis,
FPS was in mid 30; upped to 50 when a player disconnected

*Misc:
Saw an MP male with brown hair instead of green hair. Weird as
i asked a different player with green hair, he said his hair
was brown.

Like I said in previous comment, this test has a "per player" limit, so the default values (30/20) are expected to cause low FPS. Try with lower limits (10/10).

"5/5, near 1 player, 5 wanted level, about 10 cops, FPS in low 30"

If "5/5" is the ped/vehicle limit, such low FPS does not make sense. Maybe I'm going the wrong way with these changes.

Notice that you need a disconnect/reconnect after reducing limits, otherwise entities which are already synced won't be removed.

@oldnapalm "test7" version log 2:

Fresh re-load 5/5 near 1 Player, 5 wanted, 10 cops, 2 helis
FPS in mid 40 to mid 50

!!Although important bug!!

Before this, i was in another place, teled away from it to
this player, There are still 3 cop peds in that previous place.
(3 swats, teleing to them, they will fight u)

5/5, 5 wanted, near 3 players, 4 cops, near CJ house, FPS in mid 30
at times, to 40s

Near Simeon, Northern intersec to towards Union Depotd

40 fps, they arent next to me, 7 cops, 12 cops, 2 helis

hi 30 to 40, near 3 players, 5 wanted, 10 cops, 2 helis

Invisible car/bike still showed up

0/0 got hi 40s, but there were some action too as Players
were exploding cars, but still FPS stay same at 49-51
(11 cops, 2 helis)

"test7" version log 2:

Others:

Veh bug:
I hit a player in a plane, it exploded but he could still fly it
(The model is broken, no wings) Until the model is burnt

Saw him tried to spawn and getting in another plane but he was just
floating

1/1, asked player if he can see my cops, he said cant

5/5, now he said yes

Saw repeated exploding Boeing plane in LS airport
and my game crashed (No logged info)

Not sure if I understand the important bug. Synced peds not removed after teleporting away? Maybe server side distance limit is not working correctly, peds were still in range or it takes some time to remove.

This test reintroduces the client side distance limit of 200.

Good evening,

Is there a simple tutorial to be able to create your local server (two computers in the same house) I admit with the installation tutorial, I can't... I can't find my server in game

oldnapalm Author
@Micklom just enter the LAN IP address of the laptop running the server and port in the mod menu (eg 192.168.0.100:4499), the IP address is displayed in the server window (under ethernet or wi-fi interface). See https://github.com/RAGECOOP/RAGECOOP-V/wiki/Set-up-a-server (for local network you don't need port forwarding).

THANK YOU very much, continue your work is great ;)

@Micklom local server won't appear on server list, you need to type the IP address and port. Default port is 4499 (can be changed in server settings.xml) and the IP address you can check in the server console under ethernet or wi-fi (usually 192.168.x.x)

Forgive my ignorance, would installing this mod mean I could experience the whole vanilla singleplayer campaign/story as instead cooperative/multiplayer with a friend?

@Wickle you can do that, but only one player can play the story, the other(s) can only help killing enemies, driving, etc. If all players are new they can use a 100% save game like https://www.gta5-mods.com/misc/100-save-game

"test8" version log 1:

- 5-10 FPS diff 20/30 vs 5/5 standing still, not near players

Saw 1 cop visible from other Player
